Abstract

The resonant substructure of B⁰_s→D¯⁰K^-π⁺ decays is studied using a data sample corresponding to an integrated luminosity of 3.0 fb^-1 of pp collision data recorded by the LHCb detector. An excess at m(D¯⁰K^-)≈2.86 GeV/c² is found to be an admixture of spin-1 and spin-3 resonances. Therefore, the D^∗_sJ(2860)^- state previously observed in inclusive e⁺e^-→D¯⁰K^-X and pp→D¯⁰K-X processes consists of at least two particles. This is the first observation of a heavy flavored spin-3 resonance, and the first time that any spin-3 particle has been seen to be produced in B decays. The masses and widths of the new states and of the D^∗_s2(2573)^- meson are measured, giving the most precise determinations to date.
