Abstract

We perform a study of exclusive production of $D^+_sD^-_s$ , $D^{*+}_sD^-_s$ , and $D^{*+}_sD^{*-}_s$ 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 $D^+_sD^-_s$ , $D^{*+}_sD^-_s$ , and $D^{*+}_sD^{*-}_s$ mass spectra show evidence of the known $\psi$ resonances. Limits are extracted for the branching ratios of the decays $X(4260)\to D^{(*)+}_sD^{(*)-}_s$ .
