Two-loop-induced neutrino masses: A model-independent perspective

Authors :: Sierra, D. Aristizabal
Publication Year :: 2015
Abstract: We discuss Majorana neutrino mass generation mechanisms at the two-loop order. After briefly reviewing the systematic classification of one-loop realizations, we then focus on a general two-loop classification scheme which provides a model-independent catalog for neutrino mass models at the two-loop order<br />Comment: 9 pages, 5 figures.
