Query: Possible Supersymmetric Effects on Angular Distributions in $B \to K^*
  (\to K \pi) \ell^+ \ell^- $ Decays   We investigate the angular distributions of the rare B decay, $B \to K^* (\to
K \pi) \ell^+ \ell^-$, in general supersymmetric extensions of the standard
model. We consider the new physics contributions from the operators
$O_{7,8,9,10}$ in small invariant mass region of lepton pair. We show that the
azimuthal angle distribution of the decay can tell us the new physics effects
clearly from the behavior of the distribution, even if new physics does not
change the decay rate substantially from the standard model prediction.
