Abstract
It is suggested that the newly observed Y(4260) by BaBar Collaboration is a molecular state composed of an Ï and a Ïc1. Both the production and decay properties are discussed. A consequence for this molecular state, Y(4260), is that it decays into Ï+ÏâÏ0Ïc1 with similar rate to Ï+ÏâJ/Ï. It is also expected that Y(4260)âÏ0Ï0J/Ï is produced at half rate as Y(4260)âÏ+ÏâJ/Ï. These decay modes should be searched for in the B factories using initial state radiative return data and B decay data as well.
