A measurement of CP-violating observables associated with the interference of B0 → D0 K*(892)0 and B0 → anti-D0 K*(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.

Abstract

A measurement of CP-violating observables associated with the interference of B0 → D0 K*(892)0 and B0 → anti-D0 K*(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 B0s → D0 anti-K*(892)0 and B0s → anti-D0 anti-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 r_B0^DK* and δ_B0^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.
