Abstract
We analyze neutrino masses and Lepton Flavor Violation (LFV) in charged leptons with a minimal ansatz about the breaking of the U(3)5 flavor symmetry, consistent with the U(2)3 breaking pattern of quark Yukawa couplings, in the context of supersymmetry. Neutrino masses are expected to be almost degenerate, close to present bounds from cosmology and 0νββ experiments. We also predict s13≈s23{pipe}Vtd{pipe}/{pipe}Vts{pipe}≈0. 16, in perfect agreement with the recent Daya-Bay result. For slepton masses below 1 TeV, barring accidental cancellations, we expect B(μ → eγ) > 10-13 and B(τ → μγ) > 10-9, within the reach of future experimental searches. © 2012 Springer-Verlag / Società Italiana di Fisica.
