Theory and Phenomenology

In this talk I will discuss some recent developments concerning scenarios of multi-component scalar dark matter based on a single ZN symmetry.
The Schwinger-Dyson equations (DSE) were obtained from a mass functional generation $M(p)$ for a fermion propagator. The DSE are obtained, which are analogous to the Euler-Lagrange equations in Quantum field theory (QFT), since they are the equations of motion of the Green's functions . The DSE's are an infinite set of integral equations coupled to each other and it is only possible to solve...
We present a detailed study of a proposed model to explain the experimental hints of new physics in B meson decays within the frameork of the Pati-Salam unification. The model is based on the local gauge group SU$(4)_L\otimes$SU$(4)_R \otimes$SU$(2)_L \otimes$U$(1)^\prime$ and part of its gauge bosons are (3,1)2/3 vector leptoquarks. The key feature of the model is that SU$(4)_R$ is broken at...
I will talk about the Standard Model scalar coupling ($\lambda$) evolution in a particular QCD resummation scheme, where the QCD coupling becomes infrared finite due to the
presence of a dynamically generated gluon mass, leading to the existence of a non-perturbative infrared fixed point. We discuss how this scheme can be
fixed taking recourse to phenomenological considerations in the...
We present a canonical quantization for Chern-Simons
on the Null Plane coordinates using the Dirac procedure and the
Faddeev-Jackiw procedure. The constraint structure when using
null-plane coordinates is considered and the gauge generators are
derivated.
Se construye el algebra de Líe del grupo de Poincare para extenderlo a álgebras de Lie graduada adicionando generadores fermionicos. Se estudiarán representaciones irreducibles minimales de estas álgebras y los respectivos súpercampos para construir densidades lagrangianas invariantes bajo las álgebras graduadas.
We systematically review how anomaly-free 3-3-1 models, with and without exotic electric charges, can be constructed using as a basis closed sets of fermions that include each of the particles and antiparticles of all electrically charged fields. Our analysis reproduces not only the models known in the literature, but also shows the existence of several more independent models for one and...
