Inclusive J/ψ production is studied in Xe-Xe interactions at a centre-of-mass energy per nucleon pair of sNN‾‾‾‾√=5.44 TeV, using the ALICE detector at the CERN LHC. The J/ψ 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/ψ, measured in the centrality range 0-90% as well as in the centrality intervals 0-20% and 20-90% are presented. ...Inclusive J/ψ production is studied in Xe-Xe interactions at a centre-of-mass energy per nucleon pair of sNN‾‾‾‾√=5.44 TeV, using the ALICE detector at the CERN LHC.

In this Letter, the nuclear modification factors RAA for inclusive J/ψ, measured in the centrality range 0-90% as well as in the centrality intervals 0-20% and 20-90% are presented. The RAA values are compared to previously published results for Pb-Pb collisions at sNN‾‾‾‾√=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. » weiterlesen» einklappen
