Cloistered Baryogenesis
D. Aristizabal Sierra, Chee Sheng Fong, Enrico Nardi +1
The cosmological matter-antimatter asymmetry can arise from the baryon number conserving CP asymmetry in two body decays of heavy particles, when the two final states carry equal a…
Dirac neutrinos from flavor symmetry
Alfredo Aranda, Cesar Bonilla, S. Morisi +2
We present a model where Majorana neutrino mass terms are forbidden by the flavor symmetry group Delta(27). Neutrinos are Dirac fermions and their masses arise in the same way as t…
New ways to TeV scale leptogenesis
Chee Sheng Fong, M. C. Gonzalez-Garcia, Enrico Nardi +1
We show that by adding to the standard model plus the type I seesaw different types of scalars, it is possible to construct models that satisfy the three requirements of (i) genera…
Quark-Lepton Mass Relation in a Realistic A4 Extension of the Standard Model
S. F. King, S. Morisi, E. Peinado +1
We propose a realistic A4 extension of the Standard Model involving a particular quark-lepton mass relation, namely that the ratio of the third family mass to the geometric mean of…
