Latest ALICE results on J/ψ photoproduction in ultra-peripheral collisions at the LHC
Original language description
Ultra-peripheral collisions (UPCs), studied using the ALICE detector, allow us to investigate the low-x behavior of the gluon distribution of the colliding particles. Two new measurements of coherent J/ψ photoproduction cross section from Pb-Pb UPCs at sNN=5.02 TeV are presented: the first measurement of the |t|-dependence of the cross section providing a new tool to investigate the transverse gluonic structure at low Bjorken-xx and a rapidity-differential measurement at midrapidity allowing us to provide stringent constraints on nuclear gluon shadowing and saturation models. In addition, prospects for heavy vector meson photoproduction measurements in LHC Run 3 and 4 are presented.
