摘要：

Forward-backward charge asymmetry in rare dilepton B-decays is formulated with the assumption of an on-shell b-quark. We find that the asymmetry is expressed in terms of two spatially transverse helicity amplitudes, which are determined by combining the data of D --> K*(892) l(+)upsilon with heavy flavour symmetry. We estimate the charge asymmetry of B --> K*(892) l(+)l(-) for large energy leptons against various top masses in the standard model.
