Abstract
The production of J/ψ mesons is studied in proton-lead collisions at the centre-of-mass energy per
nucleon pair √sN N = 8.16 TeV with the LHCb detector at the LHC. The double differential cross-sections
of prompt and nonprompt J/ψ production are measured as a function of the J/ψ transverse momentum
and rapidity in the nucleon–nucleon centre-of-mass frame. Forward-to-backward ratios and nuclear
modification factors are determined. The results are compared with theoretical calculations based on
collinear factorisation using nuclear parton distribution functions, on the colour glass condensate or on
coherent energy loss models.
