New lepton family symmetry and neutrino tribimaximal mixing

Accepted: 20 July 2007
The newly proposed finite symmetry is applied to the problem of neutrino tribimaximal mixing. The result is more satisfactory than those of previous models based on A4 in that the use of auxiliary symmetries (or mechanisms) may be avoided. Deviations from the tribimaximal pattern are expected, but because of its basic structure, only may differ significantly from 0.5 (say 0.45) with remaining very close to unity, and very nearly zero.
