Ford, J. Roy (University of Colorado, Boulder)Abstract: Without adequate guidance from theory, the future of CP asymmetry measurements from penguin decays of the B mesons relies on the current race to measure branching fractions of these rare hadronic decays. The next generation of b-factories need these branching fractions to identify the best candidates of over a hundred modes for measurement once large samples are available. For a majority of these modes, only upper limits are known. Decay modes like B+ -> K*+ Pi0 are potential candidates for CP violation due to the multiple amplitudes contributing to the decay (which opens the door for CP violation) and the potential for a relatively high rate of production in future experiments. We improve the 90% CL Upper Limit for the B+-> K*+ Pi0 branching ration by one decade from 9.9E-5 to 8.06E-6. |
