Y(4260): Hadronic molecule versus hadro-charmonium interpretation

In this paper we confront both the hadronic molecule and the hadro-charmonium interpretations of the Y(4260) with the experimental data currently available. We conclude that the data support the Y(4260) being dominantly a D-1(D) over bar + c.c: hadronic molecule while they challenge the hadro-charmonium interpretation. However, additional data are necessary to allow for stronger conclusions.
