Charmonium production measurements in small systems at LHCb

Charmonium production in hadronic collisions provides crucial insights into heavy quark interactions with nuclear media. In this work, we present comprehensive LHCb measurements of multiple quarkonium states in small collision systems. Our results disentangle initial-state effects (such as shadowing) from final-state effects (like comover breakup), establishing constraints on the maximum local temperature reached in pPb collisions through the pattern of quarkonium survival based on binding energy.
