The data sample corresponds to an integrated luminosity of 525     fb − 1 and was recorded by the BABAR experiment at the PEP-II storage ring. The D + s D − s , D * + s D − s , and D * + s D * − s mass spectra show evidence of the known ψ resonances. Limits are extracted for the branching ratios of the decays X ( 4260 ) → D ( * ) + s D ( * ) − s .10 p.application/pdfeng(c) American Physical Society, 2010Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6019562019-04-08info:eu-repo/semantics/openAccess
