摘要：

We study electroweak penguin contributions in pure hadronic B decays in the Standard and two-Higgs-doublet models. We find that in B-s-->pi(0)(eta,phi) and B-s-->rho(0)(eta,phi) decays, the electroweak penguin contributions dominate over all other contributions. These processes provide unique signatures of electroweak penguin in pure hadronic processes. These modes could be in measurable range of future B facilities.
