Exclusive Semileptonic and Rare B Meson Decays in QCD

We present first complete results for the semileptonic and rare radiative form factors of $ mesons weak decay into a light vector meson (rho, omega, K*, phi) in the light-cone sum rule approach. The calculation includes radiative corrections, higher twist corrections and SU(3) breaking effects. The...

description We present first complete results for the semileptonic and rare radiative form factors of $ mesons weak decay into a light vector meson (rho, omega, K*, phi) in the light-cone sum rule approach. The calculation includes radiative corrections, higher twist corrections and SU(3) breaking effects. The theoretical uncertainty is investigated in detail. A simple parametrization of the form factors is given in terms of three parameters each. We find that the form factors observe several relations inspired by heavy quark symmetry.
