Electroweak Baryogenesis in the Presence of an Isosinglet Quark
G. C. Branco, D. Delepine, D. Emmanuel-Costa +1
We consider the possibility of electroweak baryogenesis in a simple extension of the standard model with an extra singlet complex scalar and a vector-like down quark. We show that…

Quasi degenerate Neutrino Masses with Universal Strength Yukawa Couplings
G. C. Branco, M. N. Rebelo, J. I. Silva-Marcos
A simple ansatz is proposed for neutrino and charged lepton mass matrices, within the framework of universal strength for Yukawa couplings. In this framework all Yukawa couplings h…
