Abstract

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 result, we use 240fb-1 of data recorded by the BABAR detector at the PEP-II asymmetric-energy e+e- storage rings at the Stanford Linear Accelerator Center running at center-of-mass energies near 10.6 GeV. © 2006 The American Physical Society.
