Le résumé fourni par la source

We present a measurement of the ${B}^{+}\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\ell}}^{+}\ensuremath{\nu}$ branching fraction based on a sample of 467 million $B\overline{B}$ pairs recorded by the BABAR detector at the SLAC PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ collider. We observe $1125\ifmmode\pm\else\textpm\fi{}131$ signal decays, corresponding to a branching fraction of $\mathcal{B}({B}^{+}\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\ell}}^{+}\ensuremath{\nu})=(1.21\ifmmode\pm\else\textpm\fi{}0.14\ifmmode\pm\else\textpm\fi{}0.08)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$, where the first error is statistical and the second is systematic. The dependence of the decay rate on ${q}^{2}$, the invariant mass squared of the leptons, is compared to QCD predictions of the form factors based on a quark model and light-cone sum rules.
