  Measurements of quarkonia production in ultra-peripheral heavy-ion collisions
are of important value to study photon-photon and photon-nucleus interactions,
the partonic structure of nuclei, and mechanisms of vector-meson production.
LHCb has studied both coherent $J/\psi$ and $\psi(2S)$ mesons in
ultra-peripheral collisions using PbPb data at forward rapidity with the
highest precision currently accessible. In addition, measurements of $Z$
production in $p$Pb collisions provide new constraints on the partonic
structure of nucleons bound inside nuclei. Here will present these measurements
of quarkonia and $Z$ production, along with comparisons with the latest
theoretical models. Measurements of quarkonia production in ultra-peripheral
