The fourth generation gives a heavy pseudo-Dirac neutral lepton, which largely decouples from other generations and is relatively stable. The framework naturally gives three active and three sterile neutrinos. We update a previous numerical analysis of a 3+3 study of the LSND anomaly, taking into account the more recent results from the MiniBooNE experiment. In particular, we study the implications for the third mixing angle sin2 θ13, as well as CP violation. We find that current data do not seriously constrain more than one sterile neutrinos. © 2010 World Scientific Publishing Company. |
