Light-cone sum rules for B → K π form factors and applications to rare decays

Abstract We derive a set of light-cone sum rules relating the hadronic form factors relevant for B → Kπℓ + ℓ − decays to the B-meson light-cone distribution amplitudes (LCDAs). We obtain the sum rule relations for all B → K π form factors of (axial)vector and (pseudo)tensor b → s currents with a P -...
