We perform a study of the exclusive production of DD̅ , D*D̅ , and D*D̅ * 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 DD̅ , D*D̅ , and D*D̅ * mass spectra show clear evidence of several ψ resonances. However, there is no evidence for Y(4260)→D*D̅ or Y(4260)→D*D̅ *.

Abstract
We perform a study of the exclusive production of DD̅ , D*D̅ , and D*D̅ * 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 DD̅ , D*D̅ , and D*D̅ * mass spectra show clear evidence of several ψ resonances. However, there is no evidence for Y(4260)→D*D̅ or Y(4260)→D*D̅ *.File in questo prodotto:
