Production of <i>χ<sub>c</sub> </i>and <i>η<sub>c</sub></i> in Ultra-Peripheral Collisions with Two-Photon Processes

Abstract

We calculate the production of c χ and c η 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 AB AHB γγ → ( c H χ = and c η ), are estimated by using the equivalent photon flux in the impact parameter space. The numerical results indicate that the study of c χ and c η in ultra-peripheral heavy ion collisions are feasible at RHIC and LHC energies.
