Measurements reveal quarkonia production mechanisms in heavy-ion collisions, suggesting new insights on particle interactions.
Measurements of quarkonia production in peripheral and ultrape-ripheral heavy-ion collisions are sensitive to photon-photon and photon-nucleus interactions, the partonic structure of nuclei, and the mechanisms of vector-meson production. In this contribution, quarkonium measurements with the highest precision currently accessible will be compared with the latest theoretical models. Additionally, new studies of ρ(770) and 0(1020) vector meson production at forward rapidity will be presented and contrasted with other experimental results. Future UPC measurements with the upgraded LHCb detector in Run 3 will also be discussed.
