Scientific Programme

  • General Discussion

  • Jet quenching

    Andy
    • Why don’t we see jet quenching in proton--proton collisions?
    • How important is system size for jet quenching?
    • What observables are particularly sensitive to jet quenching?
    • How do these observables depend on system size, particularly for small systems?
    • What observables are easy to compare between theory and experiment?
  • Particle production & freeze-out

    Vytautas
    • Does strangeness enhancement come from canonical suppression, strings or something else? Can we find an observable for this?
    • Do we have a common or flavour-dependent freeze-out in small systems? What could be a reasonable check for this?
    • How reasonable are fits from models (with freeze-out) to small systems?
    • What can we learn from charm, QCD couplings and charm balance?
    • Freeze-outs: are there single or multiple? Are they flavour dependent? Are they strangeness dependent?
    • Radial boost: How reliable are blast-waves? Are there any other ways?
  • Correlations & fluctuations

    Sumit
    • What is the origin of non-zero v_n in proton--proton (and proton--lead) collisions?
    • Are fluctuations only due to initial stages, or are they affected by the expansion of the QGP?
    • Can we separate QGP contributions to fluctuations from initial stages?
    • Do/should v_n fluctuations in proton--proton collisions show similar trends as in lead--lead collisions?
    • What are possible sources of long-range correlations in proton--proton and proton--lead collisions?
    • Balance function: Is conservation of colour charges local or global? Flow UPC/DIS?
  • CGC versus Lund strings

    Jarkko
    • What are experimental and phenomenological consequences of CGC medium modifications?
    • What is the “smoking gun signature” of saturation and can we observe it?
    • How can we incorporate the CGC in Pythia? How does the Lund string picture differ from the weak coupling/CGC picture?
