Query: Analysis of Charge Asymmetry in Rare Dilepton $B$ Decays   We analyze forward-backward charge asymmetry of the lepton production in rare
decays $B\rightarrow X_s l^+l^-$ and $B\rightarrow K^* l^+l^-$, 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.
