Description
Modifications of quarkonia production in hadronic collisions provide an im-
portant experimental observable that sheds light on the heavy quark interaction
with the nuclear medium. In small collision systems, quarkonia can suffer from
a combination of initial and final state effects such as shadowing and comover
breakup, and possible effects from a deconfined medium. The excited ψ(2S)
state, with a relatively low binding energy, is especially sensitive to these ef-
fects. In this contribution, we will present new LHCb results on J/ψ and ψ(2S)
production in high-multiplicity pp and in pPb collisions, along with comparisons
to the latest theoretical models.
