Photoproduction of Large Transverse Momentum Dimuonium (µ+ µ-) in Relativistic Heavy Ion Collisions.

The photoproduction processes of large transverse momentum (P_T) dimuonium (µ⁺ µ^-) in AA collisions is calculated. We argue that the modification of electromagnetic radiation processes at large transverse momentum (P_T > 2 GeV). Through perturbative quantum chromodynamics (_pQCD) calculation, we determine the electromagnetic production cross section of large transverse momentum dimuonium (µ⁺ µ^-) in quark-gluon plasma (QGP) at RHIC and LHC. The numerical results indicate that the contribution of photoproduction processes of dimuonium is evident in relativistic heavy ion collisions at RHIC energies and LHC energies. [ABSTRACT FROM AUTHOR]
