Abstract
Strictly adhering to the standard supersymmetric seesaw mechanism, we present a neutrino mass model which allows successful standard thermal leptogenesis compatible with gravitino cosmology. Some neutrino Yukawa couplings are naturally much larger than the naive estimates following from the seesaw formula. This leads to large BR(μâeγ), detectable in the next round of experiments. Ratios of μâeγ, Ïâeγ and Ïâμγ branching ratios are predicted in terms of the measurable neutrino mass matrix.
