Abstract
We calculate the production of χ c and η c by the two-photon process in ultra-peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies. The differential cross section of transverse momentum distribution and rapidity distribution for ( H = χ c and η c ), are estimated by using the equivalent photon flux in the impact parameter space. The numerical results indicate that the study of χ c and η c in ultra-peripheral heavy ion collisions are feasible at RHIC and LHC energies.
