Research Abstract

From the viewpoint thatthe neutrino is a key for development of the elementary particle theory,several new physics models for generating the neutrino mass were proposed. Expected signals at the LHC in these models were investigated so that reasons how the neutrino mass and the lepton flavor mixing are generated and why the neutrino mass is much smaller than those of the other elementary particles can be evident in near future.
