The QCD pomeron in ultraperipheral heavy ion collisions: IV. Photonuclear production of vector mesons

theoretical physics

Abstract.

The photonuclear production of vector mesons in ultraperipheral heavy-ion collisions is investigated within the QCD color dipole picture, with particular emphasis on the saturation model. The integrated cross section and the rapidity distribution for the \(AA \rightarrow V AA\) (\(V = \rho, \omega, \phi, J/\Psi\)) process are computed and theoretical estimates for scattering on both light and heavy nuclei are given for the energies of RHIC and LHC. A comparison with the recent STAR data on coherent production of \(\rho\) mesons is also presented. Furthermore, we calculate the photoproduction of vector mesons in proton-proton collisions at RHIC, Tevatron and LHC energies.
