Abstract
The first measurement of J/ ψ and D production in PbNe collisions by the LHCb experiment in its fixed-target configuration is reported. The production of J/ ψ and D 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 sNN=68.5GeV . The J/ ψ / D production cross-section ratio is studied as a function of rapidity, transverse momentum and collision centrality. These data are compared with measurements from pNe collisions at the same energy and show no difference in the observed J/ ψ suppression trend when comparing pNe and PbNe peripheral collisions with PbNe central collisionsFile | Dimensione del file | Formato | |
