New Prediction For Leptonic Theta13
Abstract
An extension of the neutrino sector with two right handed singlet neutrinos responsible for Dirac neutrino masses is discussed. We show that this setup with flavor symmetry can give large solar and atmospheric neutrino mixings and suppressed Theta13. The flavor symmetry U(1) x S4 is shown to lead to Theta23 = π/4 and a new predictive formula for the Theta13( 0.015).
