Abstract

The resonant substructure of B⁰_s→D¯⁰K^-π⁺ decays is studied with the Dalitz plot analysis technique. The study is based on a data sample corresponding to an integrated luminosity of 3.0 fb^-1 of pp collision data recorded by LHCb. A structure at m(D¯⁰K^-) ≈ 2.86 GeV/c² is found to be an admixture of spin-1 and spin-3 resonances. The masses and widths of these states and of the D^∗_s2(2573)^- meson are measured, as are the complex amplitudes and fit fractions for all the D¯⁰K^- and K^-π⁺ components included in the amplitude model. In addition, the D^∗_s2(2573)^- resonance is confirmed to be spin 2.
