Inclusive J/\u3c8 production in Xe\u2013Xe collisions at 1asNN = 5.44 TeV

Abstract

Inclusive J/\u3c8 production is studied in Xe\u2013Xe interactions at a centre-of-mass energy per nucleon pair of 1asNN = 5.44 TeV, using the ALICE detector at the CERN LHC. The J/\u3c8 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 RAA for inclusive J/\u3c8, measured in the centrality range 0\u201390% as well as in the centrality intervals 0\u201320% and 20\u201390% are presented. The RAA values are compared to previously published results for Pb\u2013Pb collisions at 1asNN = 5.02 TeV and to the calculation of a transport model. A good agreement is found between Xe\u2013Xe and Pb\u2013Pb results as well as between data and the model
