Abstract
We consider models where one Majorana neutrino is massless at tree level (like the see-saw with two right-handed neutrinos), and compute the contribution to its mass in generated by two-loop quantum corrections. The result is in similar to 10(-13) eV in the SM and m similar to 10(-10) eV (tan beta/10)(4) in the MSSM, compatible with the restricted range suggested by Affleck-Dine baryogenesis.
