Parallel 27: UPC

Ultra-strong electromagnetic field in relativistic heavy-ion collisions could be quantized as a large flux of linearly polarized quasi-real photons. These photons can interact with nuclei or nucleons, leading to vector meson production ($\gamma + A \rightarrow V + A$). Notably, azimuthal asymmetries between the pair momentum and the daughter momentum could arise from the linear polarization...
Ultra-peripheral collisions provide a unique environment to study pomeron-
and photon-induced reactions with heavy nuclei. These interactions can produce
a wide range of final state particles, from light vector mesons to heavy quarko-
nia, and probe potentially exotic phenomena. LHCb’s particle ID capabilities
provide unique opportunities to study hadronic final states in...
The strong electromagnetic fields associated with heavy-ions at the LHC lead to large cross sections for exclusive photoproduction of vector mesons in ultra-peripheral collisions (UPCs). Photoproduction of charmonium probes the distribution of gluons in the target nucleus. Earlier studies of charmonium photoproduction have focussed on measuring the production cross sections and rapidity...
The study of ultra-peripheral collisions (UPCs) has so far mostly focussed on exclusive production of a single vector meson or a dilepton pair, while the nuclei have remained in their ground state or have only been slightly excited. There is, however, also the possibility to study a more general class of UPCs involving a photonuclear interaction where the target nucleus is broken up, gamma+A...
