Subject: Baryogenesis via pseudo-Dirac Fermion Oscillations

In order to explain the baryon asymmetry of the Universe, we need extra CP violation, and an out-of-equilibrium process. Supersymmetric theories with a global U(1) symmetry solve the SUSY flavor and CP problems. They also have pseudo-Dirac gauginos with particle--antiparticle oscillations. If the gauginos decay out-of-equilibrium, and if there is CP violation in the oscillations, can they produce the baryon asymmetry? You should come and learn!
