Hidden charm decays of X(4014) in a D*D* molecule scenario

Inspired by the recent observation of a new structure, X(4014), in the process gamma gamma -> gamma psi(2S), we evaluate the possibility of assigning X(4014) as a D* over bar D* molecular state with I(JPC) = 0(0++) by investigating the hidden charm decays of X(4014). The partial widths of J=psi omega, eta c eta and eta c eta 0 channels are evaluated to be about (0.41-5.00), (2.05-7.49) and (0.11-0.51) MeV, respectively. Considering the experimental observation and the present estimations, we proposed to search X(4014) in the gamma gamma -> J=psi omega process in Belle II.
