Future of the ATLAS heavy ion program

The primary goal of the heavy ion program at the LHC is to study the properties of deconfined strongly interacting matter, often referred to as “quark gluon plasma” (QGP), created in ultra-relativistic nuclear collisions. That matter is found to be strongly coupled with a viscosity-to-entropy ratio near a conjectured quantum lower bound. ATLAS has undertaken a rich programme of studies using jets, Upsilons, global event properties and measurements in proton-nucleus collisions. This programme will measure fundamental transport properties of the QGP, probe the nature of the interactions between constituents of the QGP, elucidate the origin of the strong coupling, and provide insight on the initial state of nuclear collisions. The currently planned heavy ion programme through the third long shutdown should provide 1 nb-1 of sqrt(s_NN) = 5.5 TeV Pb+Pb data. That data will provide more than an order of magnitude increase in statistics over currently available data for high-pT observables such as photon-jet and Z-jet pairs. Potentially sensitive high-pT final states will remain statistically challenged and would benefit from higher-luminosity data taking.
