In this thesis we studied the top quark decays with flavor change t → cg and t → cγ mediated by a new neutral gauge boson Z′ in the context of extended models. A scenario of energies is proposed included between 2 TeV and ...

In this work, we study the effect of the quarks’ anomalous chromomagnetic moment on the solution of the Schwinger-Dyson and Bethe-Salpeter equations, with an emphasis on its implications for hadronic physics. To this end, ...
