Abstract

A measurement of CP-violating observables associated with the interference of B⁰→D⁰K^∗(892)⁰ and B⁰→D¯⁰K^∗(892)⁰ 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 B⁰_s→D⁰K¯^∗(892)⁰ and B⁰_s→D¯⁰K¯^∗(892)⁰ 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 r^DK^∗_B0 and δDK^∗_B0 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.

CP-violating observables related to the interference of B0s→D0K¯∗(892)0 and B0s→D¯0K¯∗(892)0 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 rDK∗B0 and δDK∗B0 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.
