QCD Calculation of B Meson Form Factors and Exclusive Nonleptonic Decays
Abstract
The method of QCD sum rules has proven to be particularly useful in heavy quark physics, where a small distance scale is provided by the inverse heavy quark mass. We present two new examples for the application of this method to B-physics: a calculation of the heavy-to-light form factors B → π,K and an estimate of the weak decay amplitude for B → J/ K beyond the factorization approximation.
