  Dark Matter Phenomenology of U(1) Extensions of the MSSM, Descrição: The Minimal Supersymmetric Standard Model (MSSM) is one of the best motivated models to describe new physics beyound the Standard Model (SM) at TeV scale because it provides a natural solution to the hierarchy problem, it unifies the gauge couplings at a certain grand unified scale in the vicinity of the Planck scale and it has a viable dark matter candidate, which is the neutralino. We study the dark matter phenomenology of U(1) extensions of the MSSM which are the low energy limit of a string-inspired E 6 grand unified gauge theory. These extensions of the MSSM have an interesting low energy phenomenology because they provide a natural solution to the mu problem of the MSSM and they have the right-handed sneutrino as a new viable dark matter candidate besides the neutralino.. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Felipe Almeida Gomes Ferreira - Integrante / Manuel Drees - Coordenador.

  Topologically massive spin-1 particles and spin-dependent potentials, Descrição: We investigate the role played by particular field representations of an intermediate massive spin-1 boson in the context of spin-dependent interparticle potentials between fermionic sources in the limit of low momentum transfer. The comparison between the well-known case of the Proca field and that of an exchanged spin-1 boson (with gauge-invariant mass) described by a 2-form potential mixed with a 4-vector gauge field is established in order to pursue an analysis of spin- as well as velocity-dependent profiles of the interparticle potentials. We also discuss possible applications and derive an upper bound on the product of vector and pseudo-tensor coupling constants.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (3) . , Integrantes: Felipe Almeida Gomes Ferreira - Integrante / HELAYËL-NETO, J.

  Yang-Mills Theories: An approach emerging from self-interaction and the mass problem of vector and tensor bosons, Descrição: Yang-Mills theories were proposed some decades ago and they were adopted, ever since, to describe the most elementary phenomena connected to the fundamental interactions of Nature. They set up a quite universal description and they can be used in connection with spin-1, spin-2 and even spin-3/2 force carriers. The problem with the range of the interactions can be solved up with the help of specific mechanisms, such as the spontaneous symmetry breaking. The main purpose of this Disserta- tion is to present a non-usual approach to Yang-Mills in that the whole idea of self-interactions emerges from the space-time symmetry group. The discussion of mass is carried out and, in connection with that, we can see an equivalence between a Yang-Mills model and a connected non-linear σ-model. The problem of mass generation is also applied to the spin-2 case and we discuss how a massive gravity theory may come out.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (1) . , Integrantes: Felipe Almeida Gomes Ferreira - Integrante / José Abdalla Helayël Neto - Coordenador.
