The workshop will consist of 3 half-days, devoted to the following topics:
1. Quarkonium production in proton-proton collisions at RHIC, Tevatron and the LHC (cross section, polarisation, feed-down, ...)
2. Quarkonium production in proton-nucleus and nucleus-nucleus collisions from SPS, to the LHC
3. Prospects for quarkonium production at the LHC in the fixed target mode (nuclear effects, QGP studies, TMD extraction, ...)
4. New observables in quarkonium production (quarkonium pair, quarkonium + vector boson, quarkonium + heavy quarks, Higgs to J/psi+gamma, yield and polarisation vs multiplicity, isolated quarkonium production, ...)
