We perform a study of exclusive production ofDs+Ds−, Ds+Ds−, and Ds+Ds− final states in initial-state-radiation events from e+e− annihilations at a center-of-mass energy near 10.58 GeV, to search for charmonium 1−− states. 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 Ds+Ds−, Ds+Ds−, and Ds+Ds− mass spectra show evidence of the known resonances. Limits are extracted for the branching ratios of the decays X(4260)Ds()+Ds()−.

Abstract
We perform a study of exclusive production ofDs+Ds−, Ds+Ds−, and Ds+Ds− final states in initial-state-radiation events from e+e− annihilations at a center-of-mass energy near 10.58 GeV, to search for charmonium 1−− states. 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 Ds+Ds−, Ds+Ds−, and Ds+Ds− mass spectra show evidence of the known resonances. Limits are extracted for the branching ratios of the decays X(4260)Ds()+Ds()−.File in questo prodotto:
