Abstract: The first measurement of J / ψ and D 0 production in PbNe collisions by the LHCb experiment in its fixed-target configuration is reported. The production of J / ψ and D 0 mesons is studied with a beam of lead ions with an energy of 2.5 TeV per nucleon colliding on gaseous neon targets at rest, corresponding to a nucleon-nucleon centre-of-mass energy of s NN = 68.5 GeV . The J / ψ / D 0 production cross-section ratio is studied as a function of rapidity, transverse momentum and collision centrality. These data are compared with measurements from p Ne collisions at the same energy and show no difference in the observed J / ψ suppression trend when comparing p Ne and PbNe peripheral collisions with PbNe central collisions.
