Yukawa Textures, New Physics and Nondecoupling
Gustavo C. Branco, M. N. Rebelo, J. I. Silva-Marcos
We point out that New Physics can play an important r\^ ole in rescuing some of the Yukawa texture zero ans\" atze which would otherwise be eliminated by the recent, more precise m…
A new bridge between leptonic CP violation and leptogenesis
G. C. Branco, R. Gonzalez Felipe, F. R. Joaquim
Flavor effects due to lepton interactions in the early Universe may have played an important role in the generation of the cosmological baryon asymmetry through leptogenesis. If th…
Complex CKM from Spontaneous CP Violation Without Flavor Changing Neutral Current
G. C. Branco, R. N. Mohapatra
We analyse the general constraints on unified gauge models with spontaneous CP breaking that satisfy the conditions that (i) CP violation in the quark sector is described by a real…
CP violation and limits on New Physics including recent measurements
F. J. Botella, G. C. Branco, M. Nebot
We analyse present constraints on the SM parameter space and derive, in a model independent way, various bounds on New Physics contributions to -- and --$…
