Y(4260): hadronic molecule versus hadro-charmonium interpretation
arXiv:1309.4303 · doi:10.1103/PhysRevD.89.034001
Abstract
In this paper we confront both the hadronic molecule and the hadro-charmonium interpretations of the $\y$ with the experimental data currently available. We conclude that the data support the $\y$ being dominantly a $D_1\bar D+c.c.$ hadronic molecule while they challenge the hadro-charmonium interpretation. However, additional data is necessary to allow for stronger conclusions.
