Abstract: The Dalitz plot distribution of B0 → D0K+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 Sand 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 CKM quark mixing matrix using B0 → DK+π − decays.
