Quark and Lepton Flavor Triality
Abstract
Motivated by the success of A4 in explaining neutrino tribimaximal mixing, and its approximate residual Z3 symmetry in the quark and charged-lepton sectors, the notion of "flavor triality" is proposed. Under this hypothesis, certain processes such as tau+ to mu+mu+e- and tau+ to e+e+mu- are favored, but tau+ to mu+e+e- and mu+ to e+e+e- are disfavored. Similarly, B0 to tau+e- is favored, but B0 to tau-e+ is disfavored.
