B s → Kℓν ℓ and B (s) → π(K)ℓ + ℓ − decays at large recoil and CKM matrix elements
Abstract We provide hadronic input for the B-meson semileptonic transitions to a light pseudoscalar meson at large recoil. The B s → K form factor calculated from QCD light-cone sum rule is updated, to be used for a |V ub | determination from the B s → Kℓν width. Furthermore, we calculate the hadron...
