40 Goals Rete. Quarkonii aims at studying the production of quarkonia in hadronic collisions at ultra‐relativistic energies. In the next 10 years, the future Large Hadron Collider (LHC) will open new possibilities for studying the properties of the strongly interacting matter at high temperature and the non‐perturbative features of QCD. Quarkonia will be abundantly produced and correlations with other global observables of the heavy ion collision like centrality and/or reaction plane will allow a detailed investigation of the quark‐gluon plasma (QGP) phases. In such high‐energy hadronic collisions, quarkonia will also be abundantly produced in diffractive and electromagnetic processes, including both diffractive pomeron‐ and photon‐induced quarkonium production.
