Description

We obtain the B to K l l invariant dilepton mass distribution, employing an improved light-cone sum rule calculation of B to K form factors. The SU(3)-symmetry breaking effects, including those in the K meson distribution amplitudes are updated. Utilizing the z series parameterization, we also investigate the transfer momentum dependence of transition form factors, by matching this parameterization to the light-cone sum rule predictions at small and moderate momentum transfers. Apart from the factorizable contributions of quark-lepton O9 and chromomagnetic O7 operators, some nonfactorizable effects in the B to K l l decay amplitude are also included in our analysis.
