摘要
We consider the constraints on SO(10) unified models coming from the lower limits on proton lifetime and on the scale of B - Lsymmetry breaking within the framework of the seesaw model for neutrino masses. By upgrading a triangular relationship for the inverse of nu(L) Majorana masses to the experimental situation with nonmaximal theta(23) and nonvanishing theta(13), we get for the sum of nu(L) masses the upper limit 0.16 eV.
