CP-violating baryon oscillations

We enumerate the conditions necessary for CP violation to be manifest in n - (n) over bar oscillations and build a simple model that can give rise to such effects. We discuss a possible connection between neutron oscillations and dark matter, provided the mass of the latter lies between m(p) - m(e) and m(p) + m(e). We apply our results to a possible baryogenesis scenario involving CP violation in the oscillations of the Xi(0).
