Abstract

We reassess the $B \to π ℓ ν_{ℓ}$ differential branching ratio distribution experimental data released by the BABAR and Belle Collaborations supplemented with all lattice calculations of the $B \to π$ form factor shape available to date obtained by the HPQCD, FNAL/MILC, and RBC/UKQCD Collaborations. Our study is based on the method of Padé approximants and includes a detailed scrutiny of each individual data set that allows us to obtain $| V_{u b} | = 3.51 (8)_{stat} (7)_{syst} \times 10^{- 3}$ . The semileptonic $B^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ decays are also addressed and the $η − η^{'}$ mixing discussed.
