del Amo Sanchez, P. et al. (2010) Exclusive production of D_{s}^{+}D_{s}^{-}, D_{s}^{*+}D_{s}^{-}, and D_{s}^{*+}D_{s}^{*-} via e^{+}e^{-} annihilation with initial-state radiation. Physical Review D, 82 (5). 052004. ISSN 1550-7998
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 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 ψ resonances. Limits are extracted for the branching ratios of the decays X(4260)→Ds(*)+Ds(*)-.
