摘要:
We calculate finite quantum corrections to the tribimaximal neutrino mixing pattern V-TB in three generic classes of neutrino mass models. We show that three flavor mixing angles can all depart from their tree-level results described by V-TB, among which theta(12) is most sensitive to such quantum effects, and the Dirac CP-violating phase can radiatively arise from two Majorana CP-violating phases. This theoretical scheme offers a new way to understand why theta(13) is naturally small and how three CP-violating phases are presumably correlated. (C) 2011 Elsevier B.V. All rights reserved.
