Light Dirac Neutrinos In An SU(2)ₗ× U(1)Y Model
Ghosal, Ambar
Original · EN
Light Dirac neutrino of mass of mass of the order of few eV is obtained in an SU(2)ₗ× U(1)Y model with an extended Higgs sector and right-handed neutrinos. Small neutrino mass is generated at the tree level through small effective coupling of the Dirac neutrino mass term due to soft discrete symmetry breaking. In order to remove the exact degeneracy in mass between the second and the third generation of neutrinos, one loop corrected mass terms are incorporated. The model can accommodate bi-maximal mixing scenario of neutrino which has been favoured by recent Solar and atmospheric neutrino experiments.
