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 $\alpha_s$ for the RHIC and LHC energies. It may be viewed as direct evidence of the increase of the thermal suppression of $\alpha_s$ with rising temperature.
