  Heavy meson and quarkonium properties in nuclear medium, Descrição: The project aims to study the properties of hadrons in free space and in nuclear medium. In particular, how the (effective) masses and the other properties change inside nuclear matter depending on the nuclear density. One of the main focuses is on the heavy-quarkonium (b, , c, J/) mass shifts in (symmetric) nuclear matter, and on the possibility of forming the bound states with various nuclei. The other interest is the U (1)A symmetry restoration and the and 0 meson properties in nuclear matter, and the nucleus bound states. Furthermore, the in-medium properties of the heavy-light mesons will be studied.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Kazuo Tsushima - Coordenador / Jesús Javier Cobos Martnez - Integrante / Guilherme Novais Zeminiani - Integrante.

  and -prime meson properties, and U(1)A symmetry in medium and the nucleus bound states, Descrição: Spontaneous breaking of chiral symmetry generates the nonet of massless pseudoscalar Gold-stone bosons. But the explicit breaking of U(1)A (axial) symmetry selectively shifts up the 0 -singlet (' 0 ) mass, leaving the SU(3) flavor octet of pions, K-mesons, and 8 (' ) to be massless. Then the explicit chiral symmetry breaking by non-vanishing current quark masses leads to the experimentally observed low-lying pseudoscalar meson mass spectrum of , K, and 0 mesons. Thus, U(1)A (axial) symmetry has an important role on the and 0 meson masses in free space. In nuclear medium, it was shown that the masses of and 0 are also expected to be modified in [articles published by K. Tsushima]. A detailed overview of knowledge for the and 0 meson properties in medium, for theoretically as well as for experimental, is given in the existing liturature that was studied by K. Tsushima.. The possible nucleus bound states can also be predicted by estimating the - and 0-nucleus potential including the imaginary part of the potentials.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Kazuo Tsushima - Coordenador / Jesús Javier Cobos Martnez - Integrante / Guilherme Novais Zeminiani - Integrante.

  Hadron Properties in Vacuum and Nuclear Medium from Quarks and Gluons (CNPq PQ-2, 313063/2018-4), Descrição: CNPq - Resultado do julgamento - [313063/2018-4] - Chamada CNPq N 09/2018 - Bolsas de Produtividade em Pesquisa -PQ. Key Words: Quarks and Gluons, Quantum Chromodynamics (QCD), Nuclear Medium, Quark-Meson Coupling Model, Light Front Quark Model. One of the main aims of the project is to explore the properties and structure of strongly interacting particles, known as hadrons, in free space (vacuum) and in medium (many nucleon and/or hadron environment). The objectives we deal with are the quarks, gluons, hadrons, and (hyper)nuclei. Experimental study of these objectives are tightly connected with the modern, international experimental facilities such as JLab (Thomas Jefferson National Accelerator facility in the USA), RHIC (the Relativistic Heavy Ion Collider at Brookhaven National Laboratory in the USA), Fermi National Accelerator Laboratory (in the USA), J-PARC (the Japan Proton Accelerator Research Complex), SPring-8 (Super Photon Ring 8 GeV in Japan) DESY (Deutsches Elektronen-Synchrotron in Germany), FAIR (the international Facility for Antiproton and Ion Research in Germany), COSY (Institute for Nuclear Physics in Juelich, Germany), CERN (the European Organization for Nuclear Research), and BES III (Beijing Spectrometer III in China). The dynamics of strong interaction for the quarks and hadrons, and the origin of dynamically generated masses, namely more than 90% of the proton and neutron (hadrons) masses, is described by the local gauge theory called quantum chromodynamics (QCD). These experimental facilities aim to explore the properties of the strongly interacting hadrons (baryons and mesons) involving their electroweak interaction properties. The project deals with the hadron properties theoretically in close connection with the experimental data coming out from these international facilities. In order to fully understand the changes in hadron properties in-medium, the prerequisite condition is the good understanding and of quark and gluon structure of hadrons in free space. For the hadron properties in free space, there is a great deal of accumulated data from experiments, and we can make use of them to understand and can calibrate our theoretical models. In contrast, the experimental studies for hadron properties in medium are not yet fully developed. However, with many new facilities coming on line soon and being already operated such as JLab, J-PARC, FAIR, CERN, and BES III, we are now in an excellent time to focus on such studies.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (0) . , Integrantes: Kazuo Tsushima - Coordenador., Financiador(es): Conselho Nacional de Desenvolvimento Científico e Tecnológico - Bolsa.

  Origin of (Dynamical) Mass in Visible Universe and Hadron Properties in Nuclear Medium, Descrição: The project aims to explore the properties and structure of strongly interacting particles, known as hadrons, in free space (vacuum) and in medium (many nucleon and/or hadron environment). The objectives we deal with are the quarks, gluons, hadrons, and (hyper)nuclei, where the dynamics of strong interaction for the quarks and hadrons, and the origin of dynamically generated masses, namely more than 90% of the proton and neutron (hadrons) masses, is described by a local gauge theory, quantum chromodynamics (QCD). On the other hand, the mass of the visible Universe, is carried by protons, neutrons and atomic nuclei, which are not elementary. Their masses are the result of the strong force acting between quarks and gluons, which is described by QCD. The dynamical symmetry breaking due to the strong interaction dictated by QCD (trace anomaly), gives more than 90% of hadron masses. Since hadrons, including the protons and neutrons which form the core of nuclei and atoms around us, interact strongly and are made of quarks and gluons, and the dynamics of these quarks and gluons is described by QCD, thus QCD is responsible for explaining most of the mass of the visible Universe (carried by protons, neutrons and atomic nuclei). Although QCD is believed to be the theory of the strong interaction describing the dy- namics of quarks and gluons inside hadrons, the hadrons show much richer, unexpected features which emerge from QCD but cannot be easily understood in terms of it. This feature becomes particularly evident when hadrons are immersed in medium, or surrounded by many hadrons. Thus, we are especially interested in the dense matter, the matter exists in the center of a large mass nuclei (e.g., a led nucleus), the core of neutron star, or the matter produced in high-energy heavy ion collisions. The matter (hadrons) in our universe gets most of its physical masses in free space through the spontaneous breaking of chiral symmetry and confinement (dynamical symmetry breaking in QCD). Importantly, this spontaneously broken dynamical symmetry is believed to be restored partially in medium with high hadron density and/or temperature (partial restoration of chiral symmetry). As a consequence, the masses and the properties of hadrons are expected to be modified in medium, and this is supported by several experimental facts and/or evidence, such as the EMC effect, the observed changes of bound proton electromagnetic form factors, and the formation of quark-gluon plasma phase. Thus, the core of the project is, to study the quark and gluon structure of hadrons both in free space and especially in medium, which play an important role in understanding the existence of matter (mass) in our visible Universe.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (0) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (0) . , Integrantes: Kazuo Tsushima - Coordenador / SHYAM, R. - Integrante / Gilberto Tomás Ferreira Ramalho - Integrante / Jesús Javier Cobos Martnez - Integrante / Gastão Inácio Krein - Integrante., Financiador(es): Conselho Nacional de Desenvolvimento Científico e Tecnológico - Auxílio financeiro.

  Origin of (Dynamical) Mass in Visible Universe and Hadron Properties in Nuclear Medium, Descrição: The project aims to explore the properties and structure of strongly interacting particles, known as hadrons, in free space (vacuum) and in medium (many nucleon and/or hadron environment). The objectives we deal with are the quarks, gluons, hadrons, and (hyper)nuclei, where the dynamics of strong interaction for the quarks and hadrons, and the origin of dynamically generated masses, namely more than 90% of the proton and neutron (hadrons) masses, is described by a local gauge theory, quantum chromodynamics (QCD). The discovery of the Higgs boson by the experiments with the large hadron collider (LHC) in CERN, has now fully established the Standard Model (SM). In the SM the mechanism of spontaneous symmetry breaking plays a crucial role. The spontaneously broken vacuum gets non-zero vacuum expectation value (Higgs-doublet field), and this gives the bare masses of all the massive particles in the SM, namely the quarks, leptons and the massive gauge bosons. The Standard Model unifies the description of electromagnetic and weak interactions, and explains three of the four fundamental forces of nature, namely, the strong, electromagnetic and weak interactions. On the other hand, the mass of the visible Universe, is carried by protons, neutrons and atomic nuclei, which are not elementary. Their masses are the result of the strong force acting between quarks and gluons, which is described by QCD. The dynamical symmetry breaking due to the strong interaction dictated by QCD (trace anomaly), gives more than 90% of hadron masses. Since hadrons, including the protons and neutrons which form the core of nuclei and atoms around us, interact strongly and are made of quarks and gluons, and the dynamics of these quarks and gluons is described by QCD. Thus QCD is responsible for explaining most of the mass of the "visible Universe" (carried by protons, neutrons and atomic nuclei). Although QCD is believed to be the theory of the strong interaction describing the dynamics of quarks and gluons inside hadrons and between hadrons, the hadrons show much richer, unexpected features which emerge from QCD but cannot be easily understood in terms of it.

  Analysis of tau and Heavy Meson Hadronic Decays and NeutrinoNucleus Interactions, for Hadron Structures and Interactions, and Physics beyond the Standard Model, Descrição: Programas Regulares / Auxílios a Pesquisa / Vinda de Pesquisador Visitante / Visitante do Exterior - Fluxo Contínuo: The project is to analyze current and/or forthcoming data from world-class experiments to extract hadron structures and interactions, and to search for physics beyond the standard model (BSM). The project is separated into three parts, Project A, B, C, depending on processes to be analyzed. Project A is to analyze data for hadronic tau decays into one, two, and three light mesons (pi, K, etc.) in a combined manner. A model used in the analysis consists of the light front constituent quark (LFCQ) model for hadronizations of the currents, and a phenomenological hadron interaction model for the hadronic final state interactions. Two- and three-meson scatterings are treated on the same footing by solving the scattering equations including the same hadron interactions; both two- and three-body unitarity are maintained. The analysis will provide the quark structures of hadrons, the hadron interactions, and resonance parameters for axial-vector mesons. Project B is to analyze CP violating (CPV) hadronic tau decays and also B and D decays toward a discovery of BSM physics. For this purpose, we extend the model developed in Project A to a unique analysis tool with favorable features. We conduct a preliminary study of CPV hadronic tau decays. Also, we analyze CPV data for B to D0x h decay (D0x=D0,D0-bar,h=pi,K) followed by D0x decay into three light mesons, determining one of the angles of the unitarity triangle, gamma. Finally Project C is to develop a neutrino-nucleus reaction model for the resonance region that will be crucially important in analyzing data from neutrino oscillation experiments where CPV in the lepton sector is searched for. We also improve the elementary single nucleon reaction amplitudes used in the model.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Coordenador / Satoshi Nakamura - Integrante., Financiador(es): Universidade Cruzeiro do Sul - Bolsa.

  Photoproduction of neutral mesons from nuclei, Descrição: International corporation grants by KNU: Collision of electrons or photons with nuclei or nucleons is an essential tool to investigate the structure of nuclei and elementary particles and to understand the interaction mechanisms among them. This is one of the main research themes performed at world-leading accelerator facilities such as the Thomas Jefferson National Accelerator Facility. In particular, it is expected to resolve the question whether there can be a bound state between a neutral meson and a nucleus. The interactions between neutral mesons and a nucleus is a QCD van der Waals interactions, which may be important in the interactions of nuclei and heavy flavor mesons such as the phi meson or the eta_c meson. The eta_c -nucleus and the phi-nucleus bound states were theoretically studied in the previous researches. However, not only the van der Waals forces but meson exchanges may exist in their interactions, and this will be important to reveal the possibility of the bound state and will give a clue to understand the mystery of the strong interactions. Throughout this research, we will make predictions based on various theories and will provide a way how to distinguish various mechanisms through the analyses of experimental data.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Integrante / Jesús Javier Cobos Martnez - Integrante / Yongseok Oh - Coordenador., Financiador(es): Kyungpook National University - Auxílio financeiro.

  Study of the electromagnetic and axial structure of the baryons in the vacuum and in nuclear medium (Jovem Pesquisador), Descrição: Programas Especiais / JP - Programa Jovens Pesquisadores em Centros Emergentes / Auxlio Pesquisa - Jovem Pesquisador - Fluxo Contnuo: The structure of the nucleon and other baryons can be studied using electro-weak probes. In the last years a significant amount of data were collected in the modern accelerators. To interpret those data it is fundamental the development of theoretical models. Of interest are models based on the quarks and mesons degrees of freedom. In the past the Covariant Spectator Quark Model (CSQM) was developed for the study of the internal structure of the nucleon and other light baryons based on constituent quarks (quarks with internal structure). The main goal of the project is to keep developing models for other baryons and for different physical conditions. More specifically, we are interested in the following cases: i) baryon in vacuum; ii) inclusion of quark-antiquark effects; iii) model extensions for the timelike region, in order to study resonance N* decays into nucleon (N) and electron-positron pairs (N* -> N e+e-); iv) extension of the model for nuclear medium; v) extension of the model for baryons with heavy quarks (s,c,b).. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Integrante / de Melo, Joao Pacheco B.C - Integrante / Gilberto Tomás Ferreira Ramalho - Coordenador / Satoshi Nakamura - Integrante., Financiador(es): Universidade Cruzeiro do Sul - Auxílio financeiro.

  Theoretical Studies of the Structure and Reactions of Exotic Nuclei and Many-Body Systems, Descrição: Programas Regulares / Auxílios a Pesquisa / Projeto de Pesquisa / Projeto de Pesquisa - Temático - Fluxo Contínuo: The principal objective of our research program is to develop formalisms and calculations that describe the structure and reactions of exotic nuclei. These nuclei are characterized by their low binding energy and inhomogeneous structure, consisting of a core plus halo or of two or more smaller clusters. These properties are especially important in reactions, where dissociation of the exotic nucleus is one of the dominant reaction channels. To attain the goal of this program, this group of researchers concentrates its research on models and methods (analytical and numerical) of many-body nuclear and particle physics, as well as those of atomic physics. Among the physical phenomena under study by the team are: the properties of nuclear clusters as well as the correlations between quarks and/or nucleons expected of nuclear matter and observed in finite nuclei and in reactions involving exotic or highly excited nuclei. The models developed by the group have as their goal the reproduction of experimental results and, through this, a better comprehension and/or verification of the basic laws of nature obeyed by the systems under study. The numerical and analytical methods utilized, and often developed, are focussed around the techniques needed to solve the (relativistic and nonrelativistic) dynamical equations that describe the models under study.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Integrante / Tobias Frederico - Integrante / Lauro Tomio - Integrante / Brett Vern Carlson - Coordenador / Marcelo Takeshi Yamashita - Integrante / Pedro José Pompeia - Integrante / Varese Salvador Timóteo - Integrante / Wayne Leonardo Silva de Paula - Integrante / Emanuel Vicente Chimanski - Integrante / Jorge Henrique de Alvarenga Nogueira - Integrante / Mrutunjaya Bhuyan - Integrante., Financiador(es): Instituto Tecnológico de Aeronáutica - Auxílio financeiro.

  Nuclear Physics and Applications, Descrição: National Institute of Science and Technology - Nuclear Physics and Applications (Instituto Nacional de Ciência e Tecnologia - Fsica Nuclear e Aplicações (INCT-FNA)): Nuclear physics is characterized as an important field of research that provides fundamental information on the understanding of nature, with great relevance to the knowledge and understanding of our world. This field aims at the investigation of the origin, evolution, structure, reaction mechanisms and phases of nuclear matter of strong interaction. Fundamental open questions led the nuclear physics to broaden its horizons, culminating in stunning discoveries, from the most fundamental particles such as quarks and gluons, to the dynamics of the phase transition associated with the Big Bang of the universe. Nuclear energy is a key component of energy policy. The development of new concepts in fission reactors could result in more efficient and safe reactors. Nuclear physics plays an important role in a large number of practical applications. Nuclear techniques have been widely applied in the diagnosis and treatment of diseases by means of diagnostic radiology, radiotherapy, nuclear medicine and hadrontherapy. Particle detectors, vastly used in measurements of nuclear reactions and spectrometry, are currently adapted and used in dosimetry, replacing outdated methods of images, such as radiographs, once they are fast, efficient and stable, and can achieve similar levels of precision. Industries have great interest in establish collaborations devoted to the development of nuclear instrumentation. Furthermore, the development of research in nuclear physics, through new and sophisticated experimental techniques, also enables the development of technological innovations in other areas of research. Thus, innovations in vacuum technology, cryogenics, in acquisition and data transmission systems etc, very often are a natural consequence of developments in nuclear physics. In agriculture, new varieties of plants have been created with improved characteristics by means of radiation-induced mutation. Another area of application of nuclear physics is in the investigation of radiation damage to satellites, extremely important in the area of telecommunications. Indeed, irradiation of materials by ion beams from accelerators has been used to study the effect of ionizing radiation on sensitive electronic components. In the oil industry, strategic to national development, nuclear techniques with accelerator mass spectrometry (AMS) are used for the characterization of biodiesel and stability studies of the ocean floor. Another important application of AMS is the investigation of modern climate changes. We must highlight the emerging importance of nuclear applications in nanotechnology, such as nanoelectronics, biotechnology, diagnostics and therapy. As examples: neutron scattering at small angles to allow the characterization of nano-structures, nano-dosimetry to brachytherapy induced by heavy charged particles, irradiation of electron beams to the formation of nano-gel and hardening of nano-tubes, gamma irradiation for control the size of nano-particles. In the area of pharmaceuticals, for research and production of new drugs, the phase 0 microdosing is crucial for the development of research. To this end, the ideal analytical technique is AMS, for allowing the tracking of one particle in 1015.The training of human resources in the field of nuclear physics is of great importance for the country to continue developing technology.

  Properties of Hadrons and Nuclei in Vacuum and Medium Based on Quarks and Gluons, Descrição: Programas Regulares / Auxílios a Pesquisa / Projeto de Pesquisa / Projeto de Pesquisa - Regular - Fluxo Contínuo: The large hadron collider (LHC) is now well recognized, even outside the scientific community, for its discovery of the "god particle", the Higgs boson, which gives the origin of masses for all the fundamental particles in Standard Model (SM) (issues of neutrino masses and neutrino oscillations are beyond the Standard Model). On the other hand, most of the mass of the visible Universe is carried by protons, neutrons and atomic nuclei, which are not elementary. Their masses are the result of the strong force acting between quarks and gluons, which is described by a theory known as Quantum Chromodynamics (QCD). The main aims of the research projects presented here are to explore the structure of strongly interacting particles (known as hadrons) in free space and in medium. In the latter case, we are especially interested in the dense matter, the matter exists in the center of a large mass nuclei (e.g., a led nucleus), the core of neutron star, or the matter produced in high-energy heavy ion collisions. Hadrons, including the protons and neutrons which form the core of nuclei and atoms around us, interact strongly and are made of quarks and gluons. As we already mentioned, the dynamics of these quarks and gluons is described by a local gauge theory, called QCD. For a very long period, human beings strove to find the smallest constituents of matter. So far as we know, within the limits imposed by the energies that have so far been achieved, it is believed that the quarks and gluons, the leptons and the Higgs boson, are the smallest constituents of the matter. Although QCD is believed to be the theory of the strong interaction describing the dynamics of quarks and gluons, the hadrons show much richer, unexpected features which emerge from QCD but cannot be easily understood in terms of it. This feature becomes particularly evident when hadrons are immersed in medium, or surrounded by many hadrons. In order to understand better the rich phenomena associated with hadron structure, experiments are being performed around the world in facilities such as JLab (Thomas Jefferson National Accelerator Facility in the USA), RHIC (the Relativistic Heavy Ion Collider at Brookhaven National Laboratory in the USA), Fermi National Accelerator Laboratory (in the USA), J-PARC (the Japan Proton Accelerator Research Complex), FAIR (the international Facility for Antiproton and Ion Research in Germany), COSY (Institute for Nuclear Physics in Juelich, Germany), and CERN (the European Organization for Nuclear Research, where the LHC is situated). One of the most important aims of this research proposal is to relate our theoretical investigations of the rich nature of hadronic matter, to the experimental results coming from these world wide experimental facilities. This is very important for Brazil as well as the state of Sao Paulo.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Coordenador / João Pacheco B.

  Phenomenology of the Particle Physics and Nucleus in the Light-Front Formalism, Descrição: Programas Regulares / Auxílios a Pesquisa / Projeto de Pesquisa / Projeto de Pesquisa - Regular - Fluxo Contínuo: In this project, we use the formulation of the Quantum Field Theory on the Light Front (QFTLF); in order to study the structure of mesons, baryons and light nuclei with the constituents, , i.e, in terms of its degrees of freedom of quarks and gluons, from the quantum chromodynamics (QCD). The fact of choice in use the Quantum Light-Front Field Theory formulation, it is that with this formulation have certain advantages compared with the usual formulation of the quantum field theory (equal time) which will be discussed in this project. In the light-front the quantization, we have problems related to the loss of some symmetries, among these are a loss of rotational symmetry when the Fock space is truncated. The loss of rotational invariance is treated in description of composite particles spin-0, which are the pseudoscalares mesons, such as the pion and kaon. For spin-1 particles, we have mesons, like rho meson and kaon-sta, also the deuteron. In recent work, we use component, J^+=J^0 +J^3, (plus component of the electromagnetic current) to study scalar mesons, as the pi meson and kaon and vector such as rho meson. We try extend this work to other mesons. In addition, we will study the properties of mesons and baryons, with quantum light-front field theory in dense media.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Integrante / Joao Pacheco Bicudo Cabral de Mello - Coordenador., Financiador(es): Universidade Cruzeiro do Sul - Auxílio financeiro.

  Study of meson and nucleon properties in vacuum and in nuclear medium based on the light front approach, Descrição: Programas Regulares / Auxílios a Pesquisa / Vinda de Pesquisador Visitante / Visitante do Brasil - Fluxo Contínuo: The main interests of our projects are to explore the quark structure of these strongly interacting hadrons, in free space and in medium, in terms of the electromagnetic- and weak-interactions (electroweak interactions), and strong interaction of QCD, namely by the full use of the dynamics established in Standard Model. In particular, it is believed that the matters (hadrons) in our universe get their physical masses in free space due to the spontaneous breaking of chiral symmetry, and/or by the dynamical symmetry breaking in the context of QCD. Furthermore, this spontaneously broken symmetries, are believed to be partially restored in medium with high hadron density and temperature (partial restoration of chiral symmetry). As a consequence, the masses and the properties of hadrons are expected to be modified in medium---supported by several experimental facts, such as EMC effect~\cite{EMC}, bound proton electromagnetic form factors~\cite{Strauch}, possible formation of quark-gluon plasma phase~\cite{QGP}, and the fact of stable neutron existence in nuclei. Thus, to study the quark structure of hadrons in free space and in medium, play important roles to understand the existence of matters in our universe, as the forms we can usually observe by experiments.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Integrante / Joao Pacheco Bicudo Cabral de Mello - Coordenador., Financiador(es): Universidade Cruzeiro do Sul - Bolsa.

One of the most important aims of our research projects is to relate our theoretical investigations of the rich nature of hadronic matter, to the experimental results coming from these world wide experimental facilities. This is very important for Brazil, since this field of physics will internationalize the Brazilian physicists and students. Because of the vital connection to international experimental activity, the projects will naturally stimulate international connections for both the theoretical and experimental communities in Brazil. Our projects will bring international attention and attract many international researchers to Brazil. On the other hand, the researchers in Brazil will also have the chance to visit such experimental facilities. ...... continued .....

  Hadron Physics of QCD and Quark and Gluon Dynamics, Descrição: Programas Regulares / Auxílios a Pesquisa / Vinda de Pesquisador Visitante / Visitante do Brasil - Fluxo Contínuo: To understand better the origin of hadron mass modification and restoration of chiral symmetry in a dense hadronic medium, I want to study the nucleon and hadron properties in a hot and/or dense nuclear medium. In particular, focusing on the role of the quark and gluon degrees of freedom as dictated by quantum chromodynamics,~QCD, I want to study the nuclear and hadronic phenomena, which are closely connected with experimental measurements. So far, although it may be regarded as a first crude approach, we have made extensive studies on the properties of nuclei, and hadron properties in a nuclear medium based on a relativistic quark model, the quark-meson coupling (QMC) model. A review and summary of the studies can be found in Prog. Part. Nucl. Phys. 58, 1 (2007). I would like to extend these studies further in the following directions. make a more direct connection with QCD by developing other methods and models such as the QCD sum rules, lattice QCD, and light front QCD.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Kazuo Tsushima - Integrante / Joao Pacheco Bicudo Cabral de Mello - Coordenador., Financiador(es): Universidade Cruzeiro do Sul - Bolsa.
