Abstract

We perform a study of exclusive production of Ds+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 525fb1 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 ψ resonances. Limits are extracted for the branching ratios of the decays X(4260)Ds(*)+Ds(*).
