The decays h+- -> W-+ h0(a0) within an extension of the MSSM with one complex Higgs triplet
The vertex H+-W-+h0, involving the gauge bosons W-+, the charged (H+-) and
the lightest neutral (h0) Higgs bosons, arises within the context of many
extensions of the SM, and it can be used to probe the Higgs sector of such
extensions via the decay H+- -> W+- h0. We discuss the strength of this vertex
for an extension of the MSSM with an additional complex Higgs triplet. By using
this model, we find regions of the parameter space where the decay H+- -> W+-
h0 is not only kinematically allowed, but it also becomes an important decay
mode and in some cases the dominant one.Comment: 10 figure
Charged Lepton Masses as a Possible CPV Source
We realize a model-independent study of the so-called Tri-Bi-Maximal pattern of leptonic flavor mixing. Different charged lepton mass matrix textures are studied. In particular, we are interested in those textures with a minimum number of parameters and that are able to reproduce the current experimental data on neutrino oscillation. The textures studied here form an equivalent class with two texture zeros. We obtain a Tri-Bi-Maximal pattern deviation in terms of the charged leptons masses, leading to a reactor angle and three CP violation phases non-zero. These lastest are one CP violation phase Dirac-like and two phases Majorana-like. Also, we can test the phenomenological implications of the numerical values obtained for the mixing angles and CP violation phases, on the neutrinoless double beta decay, and in the present and upcoming experiments on long-base neutrino oscillation, such as T2K, NOvA, and DUNE
