Abstract

We investigate the role that baryon number violating interactions may play in B phenomenology. Present in various grand unified theories, supersymmetric theories with R-parity violation and composite models, a fundamental diquark state could be quite light. Using the data on B decays as well as B\ensuremath-B mixing, we find strong constraints on the couplings that such a light diquark state may have with the standard model quarks. Our analysis is most general in nature, and the particular models mentioned above are only specific examples thereof.
