Resumen

Abstract: The first measurement of CP asymmetries in the decay (Formula Presented.) and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an integrated luminosity of 3.0 fb⁻¹ of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of 7 and 8 TeV. Together with constraints from B⁰ → J/ψ ρ⁰, the results are used to constrain additional contributions due to penguin diagrams in the CP -violating phase ϕ_s, measured through B_s ⁰ decays to charmonium.[Figure not available: see fulltext.]
