We observe the decays Ds1*(2710)+→D*K and DsJ*(2860)+→D*K and measure their branching fractions relative to the DK final state.

To obtain this result we use 470 fb-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.

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(+30/-5)syst) MeV/c2 having a width Γ=(239±35stat(+46/-42)syst) MeV. To obtain this result we use 470 fb-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.File in questo prodotto:
