Description

Ultra peripheral collisions provide a chance to study exclusive processes in heavy ion collisions. 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. The forward rapidity coverage of LHCb can access Byorken-xx as small as 10${}^{-6}$ and scales Q2<10Q2<10 GeV${}^2$, within the region where gluon saturation is expected. This presentation will report on the recent results on quarkonium states and the exploration of other mesons produced in elastic PbPb collisions. Future detector upgrades will increase even further the access to soft tracks using the Magnet Station tracker. Projections and new physics possibilities will also be discussed.
