Analysis of Charge Asymmetry in Rare Dilepton $B$ Decays

Abstract

We analyze forward-backward charge asymmetry of the lepton production in rare decays $B\to X_s{l}^{+}{l}^{-}$ and $B\to K^{\ast }{l}^{+}{l}^{-}$, including vector-resonance effects. Certain regions of phase space, in which the asymmetry is sensitive to individual short-distance coefficients, are pointed out. In particular, we suggest a method to test the coupling of the leptonic axial vector current to the left-handed quark current experimentally.
