Unique Signature of Electroweak Penguin In Pure Hadronic $B$ Decays

Abstract

We study elelctroweak penguin contributions in pure hadronic $B$ decays in the Standard and two-Higgs-doublet models. We find that in $B_s\to {\pi }^0(\eta ,\varphi )$ and $B_s\to {\rho }^0(\eta ,\varphi )$ decays, the electroweak penguin contributions dominate over all other contribuitons. These processes provide unique signatures of electroweak penguin in pure hadronic processes. These modes could be in measureable range of future $B$ facilities.
