Abstract

The Dalitz plot distribution of B⁰→D¯⁰K⁺π^- decays is studied using a data sample corresponding to 3.0 fb^-1 of pp collision data recorded by the LHCb experiment during 2011 and 2012. The data are described by an amplitude model that contains contributions from intermediate K^∗(892)⁰, K^∗(1410)⁰, K^∗₂(1430)⁰ and D^∗₂(2460)^- resonances. The model also contains components to describe broad structures, including the K^∗₀(1430)⁰ and D^∗₀(2400)^- resonances, in the Kπ S-wave and the Dπ S- and P-waves. The masses and widths of the D^∗₀(2400)^- and D^∗₂(2460)^- resonances are measured, as are the complex amplitudes and fit fractions for all components included in the amplitude model. The model obtained will be an integral part of a future determination of the angle γ of the Cabibbo-Kobayashi-Maskawa quark mixing matrix using B⁰→DK⁺π^- decays.
