摘要：

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*pi modes, if ReVuh is taken as negative (in standard phase convention) rather than positive. As further confirmation, we expect a lower sin2 beta value at B factories as compared to current fits, and B-s mixing close to LEP bounds at SLD and CDF.
