Effect of gluon condensate on light quark energy loss

Applying the AdS/CFT correspondence, we study the jet quenching of light quarks traversing in a deformed AdS background with backreaction due to the gluon condensate. We perform the analysis using the falling string and shooting string cases, respectively. It is found that the two methods lead to a unanimous conclusion: the inclusion of the gluon condensate enhances the energy loss. In particular, the energy loss decreases as the value of the gluon condensate decreases in the deconfined phase, and at high temperature, it is nearly not modified by the gluon condensate, in agreement with the findings of the jet quenching parameter and drag force.
