Query: Baryogenesis via Particle-Antiparticle Oscillations   CP violation, which is crucial for producing the baryon asymmetry of the
Universe, is enhanced in particle-antiparticle oscillations. We study
particle-antiparticle oscillations (of a particle with mass O(100 GeV)) with CP
violation in the early Universe in the presence of interactions with O(ab-fb)
cross-sections. We show that, if baryon-number-violating interactions exist, a
baryon asymmetry can be produced via out-of-equilibrium decays of oscillating
particles. As a concrete example we study a $U(1)_R$-symmetric,
R-parity-violating SUSY model with pseudo-Dirac gauginos, which undergo
particle-antiparticle oscillations. Taking bino to be the lightest
$U(1)_R$-symmetric particle, and assuming it decays via baryon-number-violating
interactions, we show that bino-antibino oscillations can produce the baryon
asymmetry of the Universe.
