Abstract
Inclusive J/ψproduction is studied in Xe–Xeinteractions at a centre-of-mass energy per nucleon pair of √sNN=5.44TeV, using the ALICE detector at the CERN LHC. The J/ψmeson is reconstructed via its decay into a muon pair, in the centre-of-mass rapidity interval 2.5 <y <4and down to zero transverse momentum. In this Letter, the nuclear modification factors RAAfor 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 RAAval ...
Inclusive J/ψproduction is studied in Xe–Xeinteractions at a centre-of-mass energy per nucleon pair of √sNN=5.44TeV, using the ALICE detector at the CERN LHC. The J/ψmeson is reconstructed via its decay into a muon pair, in the centre-of-mass rapidity interval 2.5 <y <4and down to zero transverse momentum. In this Letter, the nuclear modification factors RAAfor 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 RAAvalues are compared to previously published results for Pb–Pbcollisions at √sNN=5.02TeV and to the calculation of a transport model. A good agreement is found between Xe–Xeand Pb–Pbresults as well as between data and the model. ...
