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 525fb-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 ψ resonances. Limits are extracted for the branching ratios of the decays X(4260)→Ds (*)+Ds(*).
