Perspectives for quarkonium studies at the high-luminosity LHC
/ Chapon, Emilien (Beijing, Inst. High Energy Phys.) ; d'Enterria, David (CERN) ; Ducloue, Bertrand (Edinburgh U. ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Echevarria, Miguel G. (Alcala de Henares U.) ; Gossiaux, Pol-Bernard (SUBATECH, Nantes) ; Kartvelishvili, Vato (Lancaster U.) ; Kasemets, Tomas (U. Mainz, PRISMA) ; Lansberg, Jean-Philippe (IJCLab, Orsay) ; McNulty, Ronan (University Coll., Dublin) ; Price, Darren D. (Manchester U.) et al.
We review the prospects for quarkonium-production studies in proton and nuclear collisions accessible during the upcoming phases of the CERN Large Hadron Collider operation after 2021, including the ultimate high-luminosity phase, with increased luminosities compared to LHC Runs 1 and 2. We address the current experimental and theoretical open issues in the field and the perspectives for future studies in quarkonium-related physics through the exploitation of the huge data samples to be collected in proton-proton, with integrated luminosities reaching up to 3/ab, in proton-nucleus and in nucleus-nucleus collisions, both in the collider and fixed-target modes.

Heavy ions at the Future Circular Collider

(Lisbon, IST ; CERN) ; Salgado, C.A. (Santiago de Compostela U.) ; Schaumann, M. (CERN) ; van Leeuwen, M. (Utrecht U. ; NIKHEF, Amsterdam) et al.
The Future Circular Collider (FCC) Study is aimed at assessing the physics potential and the technical feasibility of a new collider with centre-of-mass energies, in the hadron-hadron collision mode, seven times larger than the nominal LHC energies. Operating such machine with heavy ions is an option that is being considered in the accelerator design studies. [...]

Heavy-flavour and quarkonium production in the LHC era: from proton-proton to heavy-ion collisions
/ Andronic, A. (Darmstadt, EMMI) ; Arleo, F. (Ecole Polytechnique ; Annecy, LAPTH) ; Arnaldi, R. (INFN, Turin) ; Beraudo, A. (INFN, Turin) ; Bruna, E. (INFN, Turin) ; Caffarri, D.

This report reviews the study of open heavy-flavour and quarkonium production in high-energy hadronic collisions, as tools to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure at high energy to deconfinement and the properties of the Quark-Gluon Plasma. Emphasis is given to the lessons learnt from LHC Run 1 results, which are reviewed in a global picture with the results from SPS and RHIC at lower energies, as well as to the questions to be addressed in the future.

J/$\psi$ production and nuclear effects in p-Pb collisions at $\sqrt{s_{NN}}$=5.02 TeV
/ ALICE Collaboration
Inclusive J/$\psi$ production has been studied with the ALICE detector in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV at the CERN LHC, in the rapidity domains 2.03 < y$_{cms}$ < 3.53 and −4.46 < y$_{cms}$ < −2.96, down to zero transverse momentum. The J/$\psi$ measurement is performed in the Muon Spectrometer through the $\mu^+\mu^−$ decay mode. [...]
