Nonzero Theta13 for Neutrino Mixing in a Supersymmetric B-L Gauge Model   with T_7 Lepton Flavor Symmetry
  We discuss how \theta_{13} \neq 0 is accommodated in a recently proposed renormalizable model of neutrino mixing using the non-Abelian discrete symmetry T_7 in the context of a supersymmetric extension of the Standard Model with gauged U(1)_{B-L}. We predict a correlation between \theta_{13} and \theta_{23}, as well as the effective neutrino mass m_{ee} in neutrinoless double beta decay.
