Exchange of high and low energy photons in ultraperipheral relativistic heavy-ion collisions

Abstract

Ultraperipheral collisions at collider energies are a useful tool to study photon-hadron (proton/nucleus) and photon-photon interactions in a hitherto unexplored energy regime. Theoretical tools to study these processes are briefly described. Some current results and problems are discussed
