  We propose that the observed baryon asymmetry of the Universe can naturally
arise from a net asymmetry generated in the sleptonic sector at fairly low
reheat temperatures. The best candidate is indeed the right-handed sneutrino.
The initial asymmetry in the sneutrino sector can be produced from the decay of
the inflaton, and is subsequently transferred into the Standard Model (s)lepton
doublet via the decay of the sneutrino. The active sphalerons then reprocess
the leptonic asymmetry into the baryonic asymmetry. The marked feature of this
scenario is that the lepton asymmetry is decoupled from the neutrino Yukawa
sector. We exhibit that our scenario can be embedded within models which seek
the origin of a tiny mass for neutrinos.
