A temperature-dependent jet-medium coupling at RHIC and LHC — •Barbara Betz — Institut für Theoretische Physik, Goethe-Universität Frankfurt, Max-von-Laue-Straße 1, D-60438 Frankfurt, Germany
The nuclear modification factor and the elliptic flow for high-pT particles up to 300 GeV are calculated for various collision energies, ranging from the low-energy runs at the Relativistic Hadron Collider (RHIC) to the high-energy collisions at the Large Hadron Collider (LHC), considering a specific class of jet energy independent models of energy loss that feature a temperature dependent jet-medium coupling. Here, the focus is on non-perturbative models, such as the Shuryak-Liao (SL) model of magnetic monopoles, in which the jet is assumed to be strongly enhanced in the vicinity of the QCD cross-over temperature. It can be shown that an assumed factor of three enhancement of the coupling near the critical temperature is sufficient to simulateously account for the pT, centrality, and √sNN dependence of both the elliptic flow and the nuclear modification factor.
