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±8stat(+305)syst)MeV/c2 having a width Γ=(239±35stat(+4642)syst)MeV. To obtain this result we use 470fb1 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.
