On the two-loop radiative origin of the smallest neutrino mass and the associated Majorana CP phase
Given a massless neutrino at a superhigh energy scale Λ (e.g., in the minimal seesaw model with only two heavy Majorana neutrinos), we calculate quantum corrections to its initially vanishing mass m1 (or m3) and the associated Majorana CP phase ρ (or ϱ) at the Fermi scale ΛF by means of the two-loop...
