Abstract:
|
We observe the decays D ∗ s 1 ( 2710 ) + → D ∗ K and D ∗ s J ( 2860 ) + → D ∗ K and measure their branching fractions relative to the D K final state. We also observe, in the D ∗ K mass spectrum, a new broad structure at a mass of ( 3044 ± 8 stat ( + 30 − 5 ) syst ) MeV / c 2 having a width Γ = ( 239 ± 35 stat ( + 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. |
