Abstract

The first study is presented of CP violation with an amplitude analysis of the Dalitz plot of B0→DK+π− decays, with D→K+π−, K+K−, and π+π−. The analysis is based on a data sample corresponding to 3.0  fb−1 of pp collisions collected with the LHCb detector. No significant CPviolation effect is seen, and constraints are placed on the angle γ of the unitarity triangle formed from elements of the Cabibbo-Kobayashi-Maskawa quark mixing matrix. Hadronic parameters associated with the B0→DK∗(892)0 decay are determined for the first time. These measurements can be used to improve the sensitivity to γ of existing and future studies of the B0→DK∗(892)0 decay.
