    Exclusive processes in Ultra Peripheral Collisions (UPCs) at the LHC and in the future EIC will provide access to the spatial distribution of small-x partons in nuclei at high energies. In particular, the transverse momentum of the produced particle, such as vector meson, is Fourier conjugate to the impact parameter.

    In this talk, we focus on vector meson production in UPCs and show how...

    3D Structure of the Nucleon: GPDs and Form Factors
    Talk

    The ALICE Collaboration has studied photonuclear interactions in ultra-peripheral heavy-ion collisions to probe gluon dynamics of protons and nuclei in a new kinematic regime at the LHC.

    Several new measurements will be presented, including the coherent J/ψ photoproduction cross section, measured as a function of the Mandelstam |t|, which provides constraints of models that consider the...

  4. 188. Polarisation-dependent studies of exclusive J/psi production in hadron-hadron and lepton-hadron interactions
    Dr Yajin Zhou (Shandong University, China)

    3D Structure of the Nucleon: GPDs and Form Factors
    Talk

    We studied polarisation-dependent exclusive J/ψ production in ultraperipheral heavy-ion collisions at RHIC and LHC energies and in eA collisions at EIC energies, in the framework of color glass condensate effective theory. The azimuthal averaged J/ψ production cross section measured by STAR and ALICE is accurately described by our calculation. We further predict significant cos 2ϕ and cos 4ϕ...
