Natural Dirac Neutrinos from Warped Extra Dimension (1006.5565v1)
Published 29 Jun 2010 in hep-ph
Abstract: Dirac neutrinos arising from gauged discrete symmetry `a la Krauss-Wilczek are implemented in the minimal custodial Randall-Sundrum model. In the case of a normal hierarchy, all lepton masses and mixing pattern can be naturally reproduced at the TeV scale set by the electroweak constraints, while simultanously satisfy bounds from lepton flavour violation. A nonzero neutrino mixing angle, $\theta_{13}$, is generic in the scenario, as well as the existence of sub-TeV right-handed Kaluza-Klein neutrinos, which may be searched for at the LHC.
