Abstract

B mesons provide an ideal laboratory for measurements of CP violation and searches for CP violation beyond the Standard Model. Recent measurements of the mixing phases of the B_s⁰ and B⁰ mesons, ϕ_s and sin2β, using decays to J/ψX final states are presented. In view of future improved measurements, a good understanding of pollution from sub-leading penguin topologies in these decays is needed. Those can be probed using suppressed decays like B_s⁰ → J/ψK_S⁰ and B_s⁰ → J/ψK^*0. Recent results using these decay modes are presented.
