EXCLUSIVE PRODUCTION OF ρ0ρ0 PAIRS IN ULTRARELATIVISTIC HEAVY ION COLLISIONS
We disuss exclusive electromagnetic production of two neutral ρ0 mesons and show the predictions for the AA → AAρ0ρ0 reactions for gold-gold collisions at the energy of and for lead-lead collisions at the energy of . The elementary cross section is calculated with the help of the vector-dominance-model (VDM)-Regge approach which usually very well describes the experimental data at large γγ energy. The low-energy γγ → ρ0ρ0 cross section is parametrized. The cross section for nuclear process is calculated by means of the equivalent photon approximation (EPA). We compare the results with realistic charge density with the results for monopole form factor.
