Description
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 $p$Pb collisions they can suffer from a combination of initial and final state effects such as shadowing and comover breakup. With high statistics from $pp$ and $p$Pb datasets, and excellent vertexing capabilities allowing separation of the prompt and $b$-decay components, LHCb performs precision measurements of J/$\psi$, $\psi(2S)$, and, for the first time at the LHC, $\chi_{c}$ production and modification. We will discuss these results, along with the first measurement of the nuclear modification factor of the exotic hadron X(3872), in context with recent model calculations.
