Observation of a new D-s meson decaying to DK at a mass of 2.86 GeV/c(2)

Observation of a new D-s meson decaying to DK at a mass of 2.86 GeV/c(2)

We observe a new Ds meson with mass (2856.6±1. 5stat±5.0syst)MeV/c2 and width (48±7stat ±10syst)MeV/c2 decaying into D0K+ and D+KS0. In the same mass distributions, we also observe a broad structure with mass (2688± 4stat±3syst)MeV/c2 and width (112±7stat ±36syst)MeV/c2. To obtain this resul...
