Z and Z' decays with and without FCNC in 331 models
A. Carcamo, R. Martinez, F. Ochoa
In the context of the 331 models, we consider constraints on the extra neutral boson predicted by the model, where three different quark family assignments are identif…
Improving bounds on flavor changing vertices in the two Higgs doublet model from mixing
Rodolfo A. Diaz, R. Martinez, Carlos E. Sandoval
We find some constraints on the flavor changing vertices of the two Higgs doublet model, from the ΔM_{B_{d}} measurement. Although bounds from this observable have already been con…
Reparameterization of the scalar potential in the two Higgs doublet model
Rodolfo A. Diaz, Viviana Dionicio, R. Martinez
In the two Higgs doublet model with no additional symmetries in the scalar sector (different from the gauge and Lorentz symmetries), it is customary to reparameterize the model by…
Z-Z' mixing in SU(3)_C X SU(3)_L X U(1)_X models with beta arbitrary
Fredy Ochoa, R. Martinez
We perform a chi ^{2} fit at 95% CL to obtain model-dependent bounds to Z-Z' mixing angle theta and Z_2-mass in the framework of SU(3)_C X SU(3)_L X U(1)_X models with beta arbitra…
Moments of inertia for solids of revolution and variational methods
Rodolfo A. Diaz, William J. Herrera, R. Martinez
We present some formulae for the moments of inertia of homogeneous solids of revolution in terms of the functions that generate the solids. The development of these expressions exp…
Renormalization Group and Grand Unification with 331 Models
Rodolfo A. Diaz, D. Gallego, R. Martinez
By making a renormalization group analysis we explore the possibility of having a 331 model as the only intermediate gauge group between the standard model and the scale of unifica…
