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.12 p.application/pdfeng(c) American Physical Society, 2009Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5777332019-04-05info:eu-repo/semantics/openAccess
