Abstract
Production of the matter-antimatter asymmetry in the B-Mesogenesis mechanism is directly related to the branching fraction of seemingly baryon number violating decays of B mesons into a light Standard Model baryon and missing energy. Achieving the observed baryon asymmetry requires that the branching fraction for such decays be greater than about 10−7–10−5. Experimental searches at B Factories and Hadron Colliders target specific decay modes. Therefore, computing the exclusive branching fraction for each decay is a critical step towards testing Mesogenesis. In this work we use QCD Light Cone Sum Rules to compute the form factors and branching fractions of the various possible channels contributing to the baryon asymmetry. Using the results, we comment on implications for current and future experimental searches.
