Abstract

The first measurement of J/ψ and D0 production in PbNe collisions by the LHCb experiment in its fixed-target configuration is reported. The production of J/ψ and D0 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 / D0 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.
