Abstract

Using the AdS/CFT duality, we study the jet quenching parameter and drag force in a deformed AdS background with backreaction due to the gluon condensate. It is shown that the two quantities both decrease as the value of the gluon condensate decreases in the deconfined phase. In addition, near the critical temperature of the QCD deconfinement transition, the gluon condensate has a stronger effect on the drag force than the jet quenching parameter.
