Quarkonia production in hadronic collisions is an important experimental observable that sheds
light on the heavy quark interaction with the nuclear medium. While the bound quarkonium states undergo dissociation and recombination in PbPb collisions, in 𝑝Pb collisions they can suffer froma combination of initial and final state effects such as shadowing and comover breakup. The exotic hadron χ𝑐1 (3872), which likely contains a cc pair plus two light quarks, may be affected by similar phenomena plus modifications of the hadronization process that emerge in dense systems. This document will discuss recent results on conventional charmonia from LHCb, and the first measurement of χ𝑐1 (3872) production in 𝑝Pb collisions.
