Abstract

A measurement of CP-violating observables associated with the interferenceof B0 → D0K⋆(892)0 and B0 →¯D0K⋆(892)0 decay amplitudes is performed in theD0 →K∓π±(π+π−), D0 →π+π−(π+π−), and D0 →K+K− final states using data collectedby the LHCb experiment corresponding to an integrated luminosity of 9 fb−1. CP-violatingobservables related to the interference of B0s →D0¯K⋆(892)0 and B0s →¯ D0¯ K⋆(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.
