Abstract: (Elsevier)
It is suggested that the newly observed Y(4260) by BaBar Collaboration is a molecular state composed of an ω and a χc1 . Both the production and decay properties are discussed. A consequence for this molecular state, Y(4260) , is that it decays into π+π−π0χc1 with similar rate to π+π−J/ψ . It is also expected that Y(4260)→π0π0J/ψ is produced at half rate as Y(4260)→π+π−J/ψ . These decay modes should be searched for in the B factories using initial state radiative return data and B decay data as well.- electron positron: annihilation
