Aspects of neutrino masses in scalar extensions of the SM

The observed neutrino mass and mixing pattern suggests that the neutrino mass generation mechanism may differ from that through which quarks and charged leptons acquire their mass. In any case, the SM must be extended in order to account for the results obtained by neutrino oscillation experiments which require neutrinos to be massive. In this seminar I will go through several scalar extensions of the SM (2HDM, 3HDM, 1SSM, 2SSM,…) and discuss (reflect about) some aspects related with neutrino masses,  lepton mixing and CP violation, as well as possible collider and cosmological implications.
