Jet suppression in non-conformal plasma using AdS/CFT

Abstract

Abstract In this paper, suppression of light quark in strongly coupled non-conformal plasmas is studied by using the AdS/CFT correspondence. According to the duality, the well-known falling string profile in the bulk is considered as a light quark moving through the plasma. The maximum distance traversed by an energetic string before falling through the horizon is interpreted as the thermalization distance of light quark in the hot, and strongly coupled plasma. Our numerical results show that the thermalization distance of light quark increases by increasing the deviation from conformal invariance. The relation between this distance and the energy of quark and the temperature of the plasma is analyzed numerically. Moreover, jet quenching parameter is calculated in this non-conformal background and it is found that the jet quenching parameter is decreased by increasing the non-conformality. Our results are compared with the results of $$ \mathcal{N}=4 $$ N = 4 SYM theory and also some available experimental data.
