### Abstract

We consider effects of strong electromagnetic fields in collisions of ultra-relativistic nuclei at the RHIC and LHC colliders. Since the parameter Zα is not small (Zα≈0.6 for Au-Au and Pb-Pb collisions), the whole series in Zα has to be summed in order to obtain the cross section with sufficient accuracy. For the production of lepton pairs we present new results related to the Coulomb corrections (corresponding to multi-photon exchange of the produced leptons with the nuclei) and to the unitarity corrections (corresponding to the exchange of light-by-light blocks between nuclei). For nuclear bremsstrahlung we calculated the unitarity corrections and a special case related to virtual Delbrück scattering.

Since the parameter Zα is not small (Zα≈0.6 for Au-Au and Pb-Pb collisions), the whole series in Zα has to be summed in order to obtain the cross section with sufficient accuracy. For the production of lepton pairs we present new results related to the Coulomb corrections (corresponding to multi-photon exchange of the produced leptons with the nuclei) and to the unitarity corrections (corresponding to the exchange of light-by-light blocks between nuclei). For nuclear bremsstrahlung we calculated the unitarity corrections and a special case related to virtual Delbrück scattering.
