Observation of Overlapping Spin-1 and Spin-3 ¯D0K− Resonances at Mass 2.86  GeV/c2

The resonant substructure of B0s→¯D0K−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(¯D0K−)≈2.86  GeV/c2 is found to be an admixture of spin-1 and spin-3 resonances. Therefore, the D∗s...
