摘要
The two-photon interactions[1]for charmonium at unprecedentedly high energies can be studied in ultra-peripheral heavy ion collisions at Relativistic Heavy Ion Collider(RHIC),Large Hadron Collider(LHC),and Future Circular Collider(FCC)energies.We investigate the semi-coherent two-photon processes for large-pT charmonium(J=)production in proton-proton and nucleus-nucleus collisions at RHIC,LHC,and FCC energies.
