Description

Exclusive photoproduction of vector mesons offers a valuable tool for probing the gluon distribution within nucleons . Measuring vector mesons of various masses over a wide range of rapidity and as a function of transverse momentum provides important information on the evolution of the gluon distribution within nuclei. Results from $J/\psi$ and $\Upsilon$(1S) mesons in pPb collisions at a center-of-mass energy per nucleon pair of 8.16 TeV, are presented as functions of squared transverse momentum and photon-proton center-of-mass energy. Comparisons between these data and theoretical models provide key constraints on the behavior of gluons inside nuclei.
