Measurement of the Decay B to Omega L Nu with the BaBar Detector and Determination of V_Ub
Nagel, Martin.
We measure the branching fraction of the exclusive charmless semileptonic decay $B \to \omega \ell \nu_{\ell}$, where $\ell$ is either an electron or a muon, with the charged $B$ meson recoiling against a tag $B$ meson decaying in the charmed semileptonic modes $B \to D \ell \nu_{\ell}$ or $B \to D^{\ast} \ell \nu_{\ell}$. The measurement is based on a dataset of 426.1 \invfb\ of \epem\ collisions at a CM energy of 10.58 \gev\ recorded with the \babar\ detector at the \pep2\ \abf\ located at the... Show Full Abstract
We measure the branching fraction of the exclusive charmless semileptonic decay $B \to \omega \ell \nu_{\ell}$, where $\ell$ is either an electron or a muon, with the charged $B$ meson recoiling against a tag $B$ meson decaying in the charmed semileptonic modes $B \to D \ell \nu_{\ell}$ or $B \to D^{\ast} \ell \nu_{\ell}$. The measurement is based on a dataset of 426.1 \invfb\ of \epem\ collisions at a CM energy of 10.58 \gev\ recorded with the \babar\ detector at the \pep2\ \abf\ located at the SLAC National Accelerator Laboratory. We also calculate the relevant $B \to \omega$ hadronic form factors to determine the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element $|V_{ub}|$.} Show Partial Abstract
