Exclusive semileptonic B → πℓν ℓ and B s → Kℓν ℓ decays through unitarity and lattice QCD

Abstract The Cabibbo-Kobayashi-Maskawa (CKM) matrix element ∣V ub ∣ is obtained from exclusive semileptonic B → πℓν ℓ and B s → Kℓν ℓ decays adopting the unitarity-based dispersion matrix approach for the determination of the hadronic form factors (FFs) in the whole kinematical range. We use lattice...
