Minimal 3-loop neutrino mass models and charged lepton flavor violation
Ricardo Cepedello, Martin Hirsch, Paulina Rocha-Morán +1
We study charged lepton flavor violation for the three most popular 3-loop Majorana neutrino mass models. We call these models "minimal" since their particle content correspond to…
Neutrino masses beyond the minimal seesaw
Ricardo Cepedello, Renato Fonseca, Martin Hirsch
The simplest possibility to generate small Majorana neutrino masses is the seesaw mechanism. However, the smallness of the observed neutrino masses can also be understood, if neutr…
Sequentially loop supressed fermion masses from a unique discrete symmetry
Carolina Arbeláez, A. E. Cárcamo Hernández, Ricardo Cepedello +2
We propose a systematic and renormalizable sequential loop suppression mechanism to generate the hierarchy of the Standard Model fermion masses from one discrete symmetry. The disc…
Radiative type-I seesaw neutrino masses
Carolina Arbeláez, A. E. Cárcamo Hernández, Ricardo Cepedello +2
We discuss a radiative type-I seesaw. In these models, the radiative generation of Dirac neutrino masses allows to explain the smallness of the observed neutrino mass scale for rat…
Systematic classification of two loop d = 4 Dirac neutrino mass models and the Diracness-dark matter stability connection
Salvador Centelles Chuliá, Ricardo Cepedello, Eduardo Peinado +1
We provide a complete systematic classification of all two-loop realizations of the dimension four operator for Dirac neutrino masses. Our classification is multi-layered, starting…
Scotogenic Dark Symmetry as a residual subgroup of Standard Model Symmetries
Salvador Centelles Chuliá, Ricardo Cepedello, Eduardo Peinado +1
We show that the scotogenic dark symmetry can be obtained as a residual subgroup of the global symmetry already present in Standard Model. We propose a general framewo…
