Scientific paper

The universe possesses an overt matter-antimatter asymmetry, quantified as the baryon-to-specific entropy ratio, knB/s?10-11+/-1. An attractive explanation is that this ratio evolved dynamically due to B, C, and CP violating interactions during a period of non-equilibrium in the GUP epoch (t∠10-35s). The out-of-equililbrium decay scenario is reviewed and detailed numerical results are discussed. A model for the requisite CP violation within the minimal SU(5) theory (one 5 and one 24 representations of Higgs) is presented. Baryosynthesis is discussed in detail for a generic superheavy boson, and a constraint on low energy unification schemes is obtained.
