The possibility of $X(4014)$ as a $D^{\ast }{\bar{D}}^{\ast }$ molecular state

Abstract

Within the framework of the local hidden gauge approach, we have studied the near-threshold interaction of the $D^{\ast }{\bar{D}}^{\ast }$ channel with quantum numbers $I(J^{PC})=0(0^{++})$, $0(2^{++})$, $1(0^{++})$, and $1(2^{++})$, respectively. The contact interaction is taken into account alone, since it is expected to give the dominant contribution near the threshold. One pole, which is found in the case of the quantum numbers $I(J^{PC})=0(0^{++})$, could be associated to the $X(4014)$ recently observed by the Belle Collaboration. Thus, we suggest that the $X(4014)$ may be an $D^{\ast }{\bar{D}}^{\ast }$ molecular state with $I(J^{PC})=0(0^{++})$, and more precise information about $X(4014)$, such as resonance parameters and decay properties, could be useful to shed light on its structure.
