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

Abstract

In this paper we confront both the hadronic molecule and the hadro-charmonium interpretations of the $\text{y}$ with the experimental data currently available. We conclude that the data support the $\text{y}$ 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.
