Abstract

Unitarity corrections to several electromagnetic processes in collisions of relativistic heavy nuclei are considered. They are due to the unitarity requirement for the S-matrix and correspond to the exchange of a light-by-light scattering block between colliding nuclei. We obtain improved results for the corrections to e⁺ e^- and μ⁺ μ^- pair production as well as new results for unitarity corrections to the production of photons via virtual Compton and virtual Delbrück scattering. These corrections can be numerically large; e.g., the μ⁺ μ^- pair production cross section is reduced by about 50% and nuclear bremsstrahlung by about 15 ÷ 20%.
