Decaying neutralino dark matter in anomalous models
D. Aristizabal Sierra, Diego Restrepo, Oscar Zapata
In supersymmetric models extended with an anomalous different R-parity violating couplings can yield an unstable neutralino. We show that in this context astrophysical and…

Lepton masses and mixing without Yukawa hierarchies
William A. Ponce, Oscar Zapata
We investigate the neutrino masses and mixing patten in a version of the model with one extra exotic charged lepton per family as introduced…
