Recent ALICE results on coherent J/psi photoproduction in ultra-peripheral Pb-Pb collisions

The strong electromagnetic fields of Pb nuclei, accelerated at the LHC, can be used to measure photon-induced interactions in a new kinematic regime. Photon-induced processes are usually studied in ultra-peripheral Pb-Pb collisions where hadronic interactions are strongly suppressed. Coherent charmo...

description The strong electromagnetic fields of Pb nuclei, accelerated at the LHC, can be used to measure photon-induced interactions in a new kinematic regime. Photon-induced processes are usually studied in ultra-peripheral Pb-Pb collisions where hadronic interactions are strongly suppressed. Coherent charmonium photoproduction is of particular interest since it is sensitive to the nuclear modification of the gluon distribution function (shadowing), which is poorly known. In this contribution, recent ALICE results on the coherent J$/\psi$ photoproduction in ultra-peripheral Pb-Pb collisions from LHC Run 2 will be presented. The implications for the study of nuclear gluon shadowing will be discussed. In addition, projections for heavy vector meson photoproduction measurements in LHC Run 3 and 4 will be presented.
