  37. Summary • ReteQuarkonii networking activities : • Database on quarkonium finished • Many fruitful discussions on soft diffractive physics at LHC • Work on pA generator at LHC • Excellent Scientific production with the new data at LHC. • Workshop RQW2010 in Nantes, School in Torino in 2011 and several meeting on diffractive physics. • Many results obtained with first PbPb run at LHC. • More results expected in the next years (WP8 of I3HP3 SaporiGravis): • Much more statistics in PbPb in 2011: J/y v2, upsilon, y’ … • pPb in 2012: Shadowing at LHC energies?

  38. Goals ReteQuarkonii 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.
