Query: Generation of Large Lepton Asymmetries   We present here a realistic model to produce a very large lepton asymmetry L
of 0.1 to 1, without producing a large baryon asymmetry. The model is based on
the Affleck and Dine scenario, in which the field acquiring a large vacuum
expectation value during inflation is a s-neutrino right. We require $L$ to be
large enough for the electroweak symmetry to be spontaneously broken at all
temperatures after inflation, with the consequent suppression of sphaleron
transitions.
