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