Abstract

We perform an analysis of jet quenching in heavy ion collisions at RHIC and LHC energies with the temperature dependent running QCD coupling. Our results show that the T-dependent QCD coupling largely eliminates the difference between the optimal values of αs for the RHIC and LHC energies. It may be viewed as direct evidence of the increase in the thermal suppression of αs with rising temperature.
