Abstract
We find in this work that the newly discovered state Y(4260), which with the mass lying in the normal charmonium spectrum energy scale, by the BaBar Collaboration could be embedded in a molecular state picture. However, in our model this molecular-like state is not constructed by the two-quark mesons, but rather by baryons, that is the baryonium. In this picture, the observed nature of this state can be easily understood, and some exclusive characters are exhibited.
