Ultraperipheral collisions (experiment)

Ultraperipheral collisions (UPC) of heavy ions and protons offer a highly interesting opportunity to study various aspects of QED and both perturbative and non-perturbative QCD. Photonuclear ($\gamma A$) and two-photon ($\gamma\gamma$) interactions are measured in various experiments at the LHC. In these proceedings, we discuss recent physics results on topics that can be studied in UPC, including nuclear shadowing, nuclear structure, precision QED and searches for physics beyond the Standard Model.
