Abstract
We perform a joint jet tomographic analysis of the PHENIX RHIC and ALICE LHC data on the nuclear modification factor RAA within the light-cone path integral approach to induced gluon emission. Our results show that variation of RAA from RHIC to LHC energies indicates that the QCD coupling constant is suppressed in the quark–gluon plasma produced at the LHC.
