ONLINE COLLOQUIUM: "Theory of heavy ions in the LHC era" by Wilke van der Schee (CERN)
Friday, 5 March 2021 from to (Europe/Amsterdam)
Heavy ion collisions quickly form a droplet of quark–gluon plasma (QGP) with a remarkably small viscosity. This smallest and hottest fluid on earth can only be understood by studying a multitude of physical stages, including a far-from-equilibrium colliding stage, a stage described by viscous relativistic hydrodynamics and as a gas of hadrons that can finally be detected by all ALICE, ATLAS, CMS and LHCb experiments at CERN. Linking all these phases I will describe how a global Bayesian analysis can leverage a wide variety of such experimental data to gain knowledge about the QGPs intrinsic properties. This knowledge can then be compared to theoretical expectations, which is particularly interesting since the quarks and gluons are strongly interacting at the relevant temperatures. The end shall give a small overview of recent interest in light ion collisions, such as pO and OO collisions as well as a wide variety of other collision systems that can be measured in fixed target mode using the SMOG2 experiment of the LHCb detector.
