Abstract

The resonant substructure of Bs0D¯0Kπ+ decays is studied with the Dalitz plot analysis technique. The study is based on a data sample corresponding to an integrated luminosity of 3.0fb1 of pp collision data recorded by LHCb. A structure at m(D¯0K)2.86GeV/c2 is found to be an admixture of spin-1 and spin-3 resonances. The masses and widths of these states and of the Ds2*(2573) meson are measured, as are the complex amplitudes and fit fractions for all the D¯0K and Kπ+ components included in the amplitude model. In addition, the Ds2*(2573) resonance is confirmed to be spin 2.
