Scalar coupling limits and diphoton Higgs decay from LHC in an model with scalar dark matter
R. Martinez, J. Nisperuza, F. Ochoa +2
In the context of an nonuniversal extension of the standard model free from anomalies, we introduce a complex scalar singlet candidate to be dark matter. In addition, an ex…
Scalar Dark Matter with CERN-LEP data and search at the LHC in an Model
R. Martinez, J. Nisperuza, F. Ochoa +1
In the framework of an nonuniversal extension of the standard model, we propose an scalar candidate for cold dark matter which exhibits interactions with ordinary matter th…
discrete group as a source of the quark mass and mixing pattern in models
A. E. Cárcamo Hernández, R. Martinez, Jorge Nisperuza
We propose a model based on the gauge symmetry with an extra discrete group, which succ…
Some phenomenological aspects of a new model
R. Martinez, J. Nisperuza, F. Ochoa +1
We propose a new non-universal extension of the standard model with the addition of three exotic quark singlets, two scalar singlets and one additional scalar doublet. We o…
Effects of quark family nonuniversality in SU(3)_c X SU(4)_L X U(1)_x models
Jorge L. Nisperuza, Luis A. Sanchez
Flavour changing neutral currents arise in the extension of the standard model because anomaly cancellation among the fermion families requir…
