Description
Vector mesons are copiously produced in ultra-peripheral
nucleus-nucleus collisions. In these collisions, the nuclei are
separated by impact parameters larger than the sum of the nuclear
radii, and the interaction is mediated by the electromagnetic
field. The interaction effectively corresponds to a photonuclear
interaction between a photon, generated from the electromagnetic field
of one of the nuclei, and the target nucleus. The ALICE Collaboration
has previously published results on exclusive J/$\psi$ photoproduction
at mid and forward rapidities in Pb-Pb collisions. The cross section
for this process is a particularly good measure of the nuclear gluon
distribution. In this talk, the latest results on exclusive production
of light and heavy vector mesons from ALICE in Pb-Pb collisions will
be presented.
