TTP09-35 Search for New Physics in Electroweak Penguins via B_s Decays

The discrepancies found in the B->pi K decays between theory and experiment suggest the presence of new physics in the electroweak penguin sector of the theory. We show that this hypothesis can be tested more efficiently including in the analysis the non-leptonic decays B_s->phi pi, B_s->phi rho.
