Résumé

A measurement of CP-violating observables associated with the interference of B⁰→ D⁰K^⋆(892)⁰ and B⁰→D¯⁰K^⋆892⁰ decay amplitudes is performed in the D⁰→ K^∓π^±(π⁺π⁻), D⁰→ π⁺π⁻(π⁺π⁻), and D⁰→ K⁺K⁻ final states using data collected by the LHCb experiment corresponding to an integrated luminosity of 9 fb⁻¹. CP-violating observables related to the interference of B_s ⁰→D⁰K¯^⋆892⁰ and B_s ⁰→D¯⁰K¯^⋆892⁰ are also measured, but no evidence for interference is found. The B⁰ observables are used to constrain the parameter space of the CKM angle γ and the hadronic parameters rB₀ ^DK⋆ and δB₀ ^DK⋆ with inputs from other measurements. In a combined analysis, these measurements allow for four solutions in the parameter space, only one of which is consistent with the world average.
