Charm and quarkonium production in collider and fixed-target mode at LHCb

Year: 2026

Type: article

Abstract: Quarkonium production in hadronic collisions is a key probe of the interaction of heavy quarks with nuclear matter. While quarkonium states can dissociate and recombine in nucleus-nucleus collisions, production in smaller systems is influenced by initial- and final-state effects such as shadowing and co-mover breakup. Thanks to excellent vertexing performance, allowing prompt and b -hadron decay components to be separated, the LHCb Collaboration has performed precise measurements of J / ψ , Υ(2 S ), and Υ( nS ) production across a wide range of collision systems. In addition to high-statistics pp and p Pb datasets at TeV energies, the SMOG2 gas injection system provides access to proton-nucleus and nucleus-nucleus collisions in fixed-target configuration at energies of ∼ 100 GeV. With the upgraded detector for LHC Run 3, LHCb can also study more central PbPb collisions than in Run 2, providing access to regions where hot-medium effects are expected to be stronger.
