Abstract

Quarkonia, i.e. bound states of b b ‾ and c c ‾ quarks, are powerful observables to study the properties of nuclear matter under extreme conditions. The formation of a Quark-Gluon Plasma (QGP), which is predicted by lattice QCD calculations at high temperatures as reached at the LHC energies, has a strong influence on the production and behavior of quarkonia. The latest ALICE results on bottomonium and charmonium production in nucleus−nucleus collisions are presented. This includes measurements of the ϒ ( 1 S ) and ϒ ( 2 S ) nuclear modification factor (R AA) at forward rapidity and the J / ψ R AA and ν 2 as a function of centrality, p T and rapidity in Pb–Pb collisions at s NN = 5.02 TeV . Also, first results from J / ψ measurements in Xe–Xe collisions at s NN = 5.44 TeV are presented. Further on, the experimental results are compared to various calculations from theoretical models.
