Dalitz plot analysis of B0s→¯D0K−π+ decays
The resonant substructure of B0s→¯D0K−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(¯D0K−)≈2.86 GeV/c2 is found to be an admixture of sp...

| Sumario: | The resonant substructure of B0s→¯D0K−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(¯D0K−)≈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 ¯D0K− and K−π+ components included in the amplitude model. In addition, the D∗s2(2573)− resonance is confirmed to be spin 2. |
