Within the framework of the local hidden gauge approach, we have studied thenear-threshold interaction of the $D^* \bar{D}^*$ 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 isexpected to give the dominant contribution near the threshold. One pole, whichis found in the case of the quantum numbers $I(J^{PC}) = 0(0^{++})$, could beassociated to the $X(4014)$ recently observed by the Belle Collaboration. Thus,we suggest that the $X(4014)$ may be an $D^* \bar{D}^*$ molecular state with$I(J^{PC}) = 0(0^{++})$, and more precise information about $X(4014)$, such asresonance parameters and decay properties, could be useful to shed light on itsstructure.

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