Abstract

New CP violating physics in b→ s transitions will modify the CP asymmetries in B decays into final CP eigenstates (ϕK_S, η^′ K_S, π⁰ K_S, ωK_S, ρ⁰ K_S and ηK_S) from their Standard Model values. In a model independent analysis, the pattern of deviations can be used to probe which Wilson coefficients get a significant contribution from the new physics. We demonstrate this idea using several well-motivated models of new physics, and apply it to current data.
