Description
Modifications of quarkonia production in hadronic collisions provide an important experimental observable to probe the heavy quark interaction with the nuclear medium. The excited ψ(2S) state, with a relatively low binding energy, is especially sensitive to these effects. Different phenomena can be probed by studying the excited-to-ground state production ratio in different collision systems with increasing multiplicity. In this contribution, we will present new LHCb results on ψ(2S) / J/ψ production from pp to PbPb collisions. In addition, progress on new measurements with Run 3 data will be reported.
