Unique signature of electroweak penguin in pure hadronic B decays

We study electroweak penguin contributions in pure hadronic B decays in the Standard and two-Higgs-doublet models. We find that in Bs → π0(ν, φ) and Bs → ϱ0 (ν, φ) 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.
