Accommodation of the Dirac Phase in the Krauss-Nasri-Trodden Model
  We investigate one of the radiative models, Kraus-Nasri-Trodden model, with the maximal value of Dirac CP violating phase, $\delta$ is -\pi/2 (or equivalently 3\pi/2), which is preferred in not only recent long baseline experiments but also the global fit of neutrino oscillation data. We show that our predicted region of the \mu-e conversion rate can be searched in the future experiments without conflicting lepton-flavor violation and dark matter constraints.
