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.
