B -> X_s γand B^+ -> l^+ νin the 2HDM type III
J. P. Idarraga, R. Martinez, N. Poveda +1
We consider the Two Higgs Doublet Model (2HDM) of type III which leads to Flavour Changing Neutral Currents (FCNC) at tree level. In the framework of this model we calculate the NL…
The rare decay in the General 2HDM type III
Rodolfo A. Diaz, R. Martinez, J-Alexis Rodriguez
We consider the branching ratio for the process in the context of the General Two Higgs Doublet Model type III. We find that taking into account reasonable values for t…
The H -> gamma gamma in Multi-Higgs doublet models
R. Martinez, J. -Alexis Rodriguez, M. Vargas
We study the dominant decays of the lightest Higgs boson in models with 2 and 3 Higgs doublets, for the case when its couplings to fermions are absent at tree-level. It is found th…
The Anomalous Chromomagnetic Dipole Moment of the Top Quark
R. Martinez, J. -Alexis Rodriguez, M. Vargas
We calculate the one loop corrections to the chromomagnetic dipole moment of the top quark in the framework of the Standard Model, the two Higgs doublet model and the Minimal Super…
