Abstract: In this talk I will describe a new mechanism for baryogenesis at the 1-200 MeV scale. In this mechanism 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. I will 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.
