  We propose a new mechanism for baryogenesis at the 1-200 MeV scale.
Enhancement of CP violation takes place via interference between oscillations
and decays of mesinos--bound states of a scalar quark and antiquark and their
CP conjugates. We present the mechanism in a simplified model with four new
fundamental particles, with masses between 300 GeV and 10 TeV, and show that
some of the experimentally allowed parameter space can give the observed
baryon-to-entropy ratio.
