Abstract
We study the fine splitting in charmonium spectrum in quark model with the channel coupling effect, including DD, DD*, D*D* and DsDs, DsDs*, Ds*Ds* channels. The interaction for channel coupling is constructed from the current-current Lagrangian related to the color confinement and the one-gluon exchange potentials. By adopting the massive gluon propagator from the lattice calculation in the nonperturbative region, the coupling interaction is further simplified to the four-fermion interaction. The numerical calculation still prefers the assignment 1+ + of X(3872).
