Implication of MINOS results to neutrino masses

초록

We analyzed the results of Main Injector Neutrino Oscillation Search (MINOS) that constrain the neutrino mixing angles theta (13) and theta (23) in combination. According to the exclusion curve obtained from recent experimental results, the mass spectrum of the normal hierarchy is disfavored. A model is constructed and examined to explain the compatibility of the model and the phenomenologically allowed parameter region in sin theta (23) vs. sin theta (13). The prediction of the model, which contains certain criteria in the ratio of non-Standard Model additional Higgs scales, results in an inverted hierarchy in masses, 1 < m (2)/m (3) < 1.7.
