Abstract

Using 13.3fb-1 of e+e- collision data taken in the Υ(1S-4S) region with the CLEO III detector at the CESR collider, a search has been made for the new resonance Y(4260) recently reported by the BABAR Collaboration. The production of Y(4260) in initial state radiation (ISR), and its decay into π+π-J/ψ, are confirmed. A good quality fit to our data is obtained with a single resonance. We determine M(Y(4260))=(4284-16+17(stat) ±4(syst))MeV/c2, Γ(Y(4260))=(73-25+39(stat)±5(syst))MeV/c2, and Γee(Y(4260))×B(Y(4260)→π+π-J/ψ)=(8.9-3.1+3. 9(stat)±1.8(syst))eV/c2.
