Classically Conformal Radiative Neutrino Model with Gauged B-L Symmetry
  We discuss a classically conformal radiative neutrino model with gauged B$-$L symmetry, in which the B$-$L symmetry breaking can occur through the Coleman-Weinberg mechanism. As a result, Majorana mass term is generated and EW symmetry breaking also occurs. We show some allowed parameters to satisfy several theoretical and experimental constraints. Theoretical constraints are inert conditions and Coleman-Weinberg condition. Experimental bounds are lepton flavor violation(especially \mu -> e \gamma), the current bound on the $Z'$ mass at LHC, in additions to the neutrino oscillations.
