Abstract: | We perform a study of the exclusive production of D ¯¯¯ D , D ∗ ¯¯¯ D , and D ∗ ¯¯¯ D ∗ in initial-state-radiation events, from e + e − annihilations at a center-of-mass energy near 10.58 GeV, to search for charmonium and possible new resonances. The data sample corresponds to an integrated luminosity of 384 fb − 1 and was recorded by the BABAR experiment at the PEP-II storage rings. The D ¯¯¯ D , D ∗ ¯¯¯ D , and D ∗ ¯¯¯ D ∗ mass spectra show clear evidence of several ψ resonances. However, there is no evidence for Y ( 4260 ) → D ∗ ¯¯¯ D or Y ( 4260 ) → D ∗ ¯¯¯ D ∗ . |
