Determination of the Phase of Vub from Charmless Hadronic B Decay Rates

Wei-Shu Hou, James G. Smith, Frank Würthwein

We perform a model dependent fit to recent data on charmless hadronic B decays and determine $\gamma$, the phase of $V_{ub}^{\ast }$. We find $\gamma =114_{-21}^{+25}$ degrees, which disfavors the…
