Neutrino Masses and Mixing Matrix from SU(1,1) Horizontal Symmetry
arXiv:hep-ph/0305297 · doi:10.1143/PTP.110.1087
Abstract
A new mechanism is proposed to explain neutrino masses and their mixing via SU(1,1) horizontal symmetry breaking. Based on this mechanism smallness of neutrino masses is naturally realized and inverted hierarchical spectrum with large mixing is given.
