$${{J}/\psi }$$ and $${{D}} ^0$$ production in $$\sqrt{s_{\scriptscriptstyle \text {NN}}} =68.5\,\text {GeV} $$ PbNe collisions

The European Physical Journal C, vol. 83

Abstract

Abstract The first measurement of $${{J}/\psi }$$ J / ψ and $${{D}} ^0$$ D 0 production in PbNe collisions by the LHCb experiment in its fixed-target configuration is reported. The production of $${{J}/\psi }$$ J / ψ and $${{D}} ^0$$ D 0 mesons is studied with a beam of lead ions with an energy of 2.5 $$\,\text {TeV}$$ TeV per nucleon colliding on gaseous neon targets at rest, corresponding to a nucleon-nucleon centre-of-mass energy of $$\sqrt{s_{\scriptscriptstyle \text {NN}}} =68.5\,\text {GeV} $$ s NN = 68.5 GeV . The $${{J}/\psi }$$ J / ψ / $${{D}} ^0$$ 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 $$p\text {Ne}$$ p Ne collisions at the same energy and show no difference in the observed $${{J}/\psi }$$ J / ψ suppression trend when comparing $$p\text {Ne}$$ p Ne and PbNe peripheral collisions with PbNe central collisions.
