Physics implications of neutrinoless double beta decay are summarized. Both the standard approach of light neutrino exchange as well as non-standard interpretations in terms of TeV scale physics will be discussed. Tests of the mechanisms at colliders and with lepton flavor violation are presented. It is pointed out that left-right symmetric mechanisms can have testable consequences also in...

We propose a three-loop radiative neutrino (R\nu) mass model realized with BSM fields,
including minimal-dark-matter (MDM) candidates. These, in conjunction with the 2HDM fields
on top of which the model is built, lead to an accidental Z_2 symmetry protecting the fermion
quintuplet as a DM candidate. We assess the potential fingerprints of the Majorana quintuplet
on present and future pp colliders.

Majorana neutrino masses can originate either at the tree level
(type-I, II or III seesaws) or can be radiatively induced. The latter
option naturally requires order TeV BSM fields, thus leading to
testable neutrino mass generation mechanisms. Based on a two-loop
systematic classification of the dimension five effective Weinberg
operator, in this talk I will discuss the different...

Leptogenesis is an appealing framework to explain the baryon asymmetry of the universe. In its standard realization involving right-handed neutrinos, it has been shown that, if right-handed neutrinos are hierarchical, the flavour structure of Boltzmann equations describing the evolution of the lepton asymmetry simplifies a lot. When the charged lepton Yukawa are negligible, that is when the...
