General parametrization of Majorana neutrino mass models
Isabel Cordero-Carrión, Martin Hirsch, Avelino Vicente
We discuss a general formula which allows to automatically reproduce experimental data for Majorana neutrino mass models, while keeping the complete set of the remaining model para…
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…
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…
Quasi-Dirac neutrino oscillations at DUNE and JUNO
G. Anamiati, V. De Romeri, M. Hirsch +2
Quasi-Dirac neutrinos are obtained when the Lagrangian density of a neutrino mass model contains both Dirac and Majorana mass terms, and the Majorana terms are sufficiently small.…
Long-lived heavy particles in neutrino mass models
Carolina Arbeláez, Juan Carlos Helo, Martin Hirsch
All extensions of the standard model that generate Majorana neutrino masses at the electro-weak scale introduce some "heavy" mediators, either fermions and/or scalars, weakly coupl…
Exotic coloured fermions and lepton number violation at the LHC
E. Carquin, J. C. Helo, M. Hirsch +1
Majorana neutrino mass models with a scale of lepton number violation (LNV) of order TeV potentially lead to signals at the LHC. Here, we consider an extension of the standard mode…
