Abstract
We observe the decays Ds1*(2710)+-->D*K and DsJ*(2860)+-->D*K and measure their branching fractions relative to the DK final state. We also observe, in the D*K mass spectrum, a new broad structure at a mass of (3044±8[subscript stat](+30/-5)[subscript syst]) MeV/c[superscript 2] having a width Gamma=(239±35[subscript stat](+46/-42)[subscript syst]) MeV. To obtain this result we use 470 fb[superscript -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.
