abstract
Due to coherence, there are strong electromagnetic fields of short duration in very peripheral collisions. They give rise to photon-photon and photon-nucleus collisions with a high flux up to an invariant mass region hitherto unexplored experimentally. After a general survey of the field equivalent photon numbers and photon-photon luminosities, especially for relativistic heavy ion collisions, are discussed. Special care needs to be taken to include the effects of the strong interaction and nuclear size in this case. Photon-photon and photon-hadron physics at various invariant mass scales are then discussed. The maximum equivalent photon energy in the lab-system (collider frame) are typically of the order of 3 GeV for RHIC and 100 GeV for LHC. Diffractive processes are an important background process. Lepton-pair, especially electron-positron pair production is copious. Due to the strong fields there will be new phenomena, like multiple e+e- pair production. The experimental techniques to select gamma-gamma-processes are finally discussed together with important background processes.

Color dipole calculations of the ratio of exclusive vector meson to inclusive jet/hadron photoproduction cross sections in UPC pA and AA collisions at LHC Run 4, including the double ratio R_UPC proposed for saturation studies.
Computes production cross sections and sensitivity limits for heavy ALPs in light-by-light scattering at FCC-hh across pp, pPb, and PbPb modes.
Improved tensor-pomeron model for π⁺π⁻ photoproduction and central exclusive production in pp collisions that accounts for different subenergies in the Drell-Söding contribution and yields larger cross sections with more skewed ρ⁰ lineshape.
