Variation of jet quenching from RHIC to LHC and thermal suppression of QCD coupling constant
Abstract
We perform a joint jet tomographic analysis of the data on the nuclear modification factor RAA from PHENIX at RHIC and ALICE at LHC. The computations are performed accounting for radiative and collisional parton energy loss with running coupling constant. Our results show that the observed slow variation of RAA from RHIC to LHC indicates that the QCD coupling constant is suppressed in the quark-gluon plasma produced at LHC.
