29 Jan 2013 | Abstract: | We propose a realistic A4 extension of the Standard Model involving a
particular quark-lepton mass relation, namely that the ratio of the third
family mass to the geometric mean of the first and second family masses are
equal for down-type quarks and charged leptons. This relation, which is
approximately renormalization group invariant, is usually regarded as arising
from the Georgi-Jarlskog relations, but in the present model there is no
unification group or supersymmetry. In the neutrino sector we propose a simple
modification of the so called Zee-Wolfenstein mass matrix pattern which allows
an acceptable reactor angle along with a deviation of the atmospheric and solar
angles from their bi-maximal values. Quark masses, mixing angles and CP
violation are well described by a numerical fit. | Source: | arXiv, 1301.7065 | Services: | Forum | Review | PDF | Favorites |
