Relativistic heavy ions are sources of strong electromagnetic fields which produce photon-induced interactions. These interactions are usually studied in ultra-peripheral collisions (UPCs) of the relativistic heavy ions. The UPCs can produce di-lepton or di-hadron pairs via the γ-γ interactions or produce vector mesons via the γ-nuclear interactions. Both the photo-produced vector mesons and...
In this talk, we will present the recent experimental results on the physics of ultra-peripheral heavy ion collisions using the ALICE detector, including the measurements of both heavy and light vector mesons in both ultra-peripheral p-Pb and Pb-Pb collisions.
Relativistic heavy-ion beams at the LHC are accompanied by a large flux of equivalent photons, leading to multiple photon-induced processes. This talk presents a series of measurements of such processes performed by the ATLAS Collaboration. Measurements of exclusive dilepton production (electron, muon, and tau pairs) are discussed. These processes provide strong constraints on the nuclear...
Overview of latest UPC results from CMS.
Ultra peripheral collisions has a large range of observables which are kinematically hard to be measured. These includes light vector mesons from coherent effects and other probes requiring soft particle tracking. The LHCb experiment has unique capabilities to study multiple UPC observables, thanks to its low transverse momentum tracking and particle identification. This presentation will...
