Inclusive J/$\psi$ production in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.44 TeV

Abstract

Inclusive J/$\psi$ production is studied in Xe-Xe interactions at a centre-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}=5.44$ TeV, using the ALICE detector at the CERN LHC. The J/$\psi$ meson is reconstructed via its decay into a muon pair, in the centre-of-mass rapidity interval $2.5<y<4$ and down to zero transverse momentum. In this Letter, the nuclear modification factors $R_{\mathrm{AA}}$ for inclusive J/$\psi$, measured in the centrality range 0-90% as well as in the centrality intervals 0-20% and 20-90% are presented. The $R_{\mathrm{AA}}$ values are compared to previously published results for Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV and to the calculation of a transport model. A good agreement is found between Xe-Xe and Pb-Pb results as well as between data and the model.
