Abstract:
A measurement of CP -violating observables associated with the interference of B0 → D0K⋆(892)0 and B0 → D0K⋆(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 Bs0 → D0K⋆(892)0 and Bs0 → D0K⋆(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 rB0DK⋆ and δB0DK⋆ 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.
