Indications for Factorization and $Re{V}_{ub}<0$ from Rare B Decay Data

Abstract

Surveying known hadronic rare B decays, we find that the factorization approximation can give a coherent account of $K\pi$, $\pi \pi$ and ${\rho }^0{\pi }^{+}$ data and give predictions for ${\omega }^0{\pi }^{+}$, $\rho \pi$ and $K^{\ast }\pi$ modes, {\it if $Re{V}_{ub}$ is taken as negative} (in standard phase convention) rather than positive. As further confirmation, we expect a lower $\sin 2\beta$ value at B Factories as compared to current fits, and $B_s$ mixing close to LEP bounds at SLD and CDF.
