Abstract

Inspired by the recent observation of a new structure, X(4014)X(4014), in the process γγγψ(2S)\gamma\gamma\to \gamma\psi(2S), we evaluate the possibility of assigning X(4014)X(4014) as a DDˉD^\ast \bar{D}^\ast molecular state with I(JPC)=0(0++)I(J^{PC})=0(0^{++}) by investigating the hidden charm decays of X(4014)X(4014). The partial widths of J/ψωJ/\psi\omega, ηcη \eta_{c}\eta and ηcη\eta_{c}\eta^{\prime} channels are evaluated to be about (0.415.00)(0.41\sim 5.00), (2.057.49)(2.05\sim7.49) and (0.110.51) MeV(0.11\sim0.51)\ \mathrm{MeV}, respectively. Considering the experimental observation and the present estimations, we proposed to search X(4014)X(4014) in the γγJ/ψω\gamma \gamma \to J/\psi \omega process in Belle II.
