Calculation of the branching ratio of B-→hc+K- in perturbative QCD
Abstract
The branching ratio of B-→hc+K- is re-evaluated in the PQCD approach. In this theoretical framework all the phenomenological parameters in the wave functions and Sudakov factor are priori fixed by fitting other experimental data, and in the whole numerical computations we do not introduce any new parameter. Our results are consistent with the upper bounds set by the BABAR and Belle measurements.
