Abstract

The measured branching ratio by CLEO collaboration at Cornell University in USA for B ->r| ’K decay, with large statistical error, is not consistent with the theoretically predicted values. In this paper we discuss several important theoretical models that were presented before and after the CLEO measurement. The possibility to obtain accurate value of branching ratio and/or to knew the reason of this discrepancy in near future are also discussed using the simulation data obtained by using the BELLE detector at KEK in Japan.
