Description
The study of the production of quarkonia in heavy-ion collisions represents one of the most important tools for the characterization of the Quark-Gluon Plasma. In particular, the screening of the color force in a deconfined medium is predicted to lead to a suppression of the production of charmonium and bottomonium states with respect to the yields observed in pp collisions. At the same time, re-generation mechanisms between deconfined heavy quarks, during the QGP phase or when the system hadronizes, may lead to an increased production.
Extended studies on quarkonium have been carried out at the LHC in Pb-Pb collisions, up to a center-of-mass energy per nucleon-nucleon collision $\sqrt{s_{\rm NN}}=5.02$ TeV. Results on several charmonium (J/$\psi$, $\psi(2S)$) and bottomonium ($\Upsilon(1S)$, $\Upsilon(2S)$, $\Upsilon(3S)$) states are available.
In this talk I will review the main achievements of the LHC program and discuss their implications for QGP studies.
