The unequal masses of the charged leptons then induce a computable neutrino mass matrix with splittings and mixings through the electroweak interactions. In this way the Standard Model including quantum gravity can accommodate and predict the neutrino masses and mixings. Some consequences are pointed out.4 pagesHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
