Query: QCD Sum Rule Analysis of B \to (K,K^*) (\ell^+\ell^-,\nu\bar\nu) Decays   We use three-point QCD sum rules to calculate the form factors governing the
rare exclusive decays B \to (K,K^*) \ell^+ \ell^-, B \to (K,K^*) \nu \bar\nu.
We predict the branching ratios, the invariant mass distributions of the lepton
pair for B \to (K,K^*) \ell^+ \ell^-, and the spectra of missing energy for B
\to (K,K^*) \nu \bar\nu. The forward-backward asymmetry in B \to K^* \ell^+
\ell^- provides us with interesting tests of the Standard Model and its
extensions.
