Non-zero \theta_{13} linking to Dark Matter from Non-Abelian Discrete Flavor Model in Radiative Seesaw

Abstract

We propose a new scenario in a radiative seesaw model based on A_4 flavor symmetry. In this model, we explore a possibility of linking non-zero \theta_{13} to dark matter. And we analyze the lepton sector to predict the observed neutrinos and mixings, especially obtaining a lower bound of \theta_{13}~3.5 [Deg.]. We show that the non-zero \theta_{13} is correlated with our heavy Majorana type of dark matter. Also we predict that the mass be O(1-10) TeV, as a result of analyzing the Wilkinson-Microwave-Anisotropy-Probe and lepton flavor violation.
