Rare top quark decay t --> u_1 \bar{u}_2 u_2 in the standard model
Adriana Cordero-Cid, J. M. Hernandez, G. Tavares-Velasco +1
The one-loop induced top quark decay () is calculated in the context of the standard model. The dominant contribution to this top quark decay arises…
Effective Lagrangian approach to Higgs-mediated FCNC top quark decays
Adriana Cordero-Cid, M. A. Perez, G. Tavares-Velasco +1
The flavor changing neutral current (FCNC) transitions t --> q'H and t --> q'V_i (V_i=γ, g, Z) are studied in the context of the effective Lagrangian approach. We focus on the scen…
Static quantities of a neutral bilepton in the 331 model with right-handed neutrinos
G. Tavares-Velasco, J. J. Toscano
A neutral vector boson can possess static electromagnetic properties provided that the associated field is no self-conjugate. This possibility is explored in the $SU_C(3) X SU_L(3)…
Fermion contribution to the static quantities of arbitrarily charged vector bosons
G. Tavares-Velasco, J. J. Toscano
We present an analysis of the one-loop contribution from left- and right-handed fermions to the static electromagnetic properties of an arbitrarily charged no self-conjugate vector…
Decay H^+ -> W^+ gamma in a nonlinear R_xi-gauge
J. Hernandez-Sanchez, M. A. Perez, G. Tavares-Velasco +1
A new evaluation of the charged Higgs boson decay is presented in the context of the general two-Higgs doublet model. A nonlinear -gauge which considerably simpl…
Two-body decays in the minimal 331 model
M. A. Perez, G. Tavares-Velasco, J. J. Toscano
The two-body decays of the extra neutral boson Z_2 predicted by the minimal 331 model are analyzed. At the three-level it can decay into standard model particles as well as exotic…
