Abstract

From e+e- collision data acquired with the CLEO-c detector at CESR, we search for the non-DD̄ decays ψ(3770)→γχcJ, with χcJ reconstructed in four exclusive decays modes containing charged pions and kaons. We report the first observation of such decays for J=0 with a branching ratio of (0.73±0.07±0.06)%. The rates for different J are consistent with the expectations assuming ψ(3770) is predominantly a 13D1 state of charmonium, but only if relativistic corrections are applied.
