Light quark energy loss in strongly coupled [formula omitted] SYM plasma with magnetic field

Abstract

We employ the AdS/CFT correspondence to study the jet quenching of light quarks traversing in strongly coupled N=4 supersymmetric Yang-Mills (SYM) plasma under the influence of a (constant) magnetic field. We perform the analysis using falling string and shooting string, respectively. It is found that the two methods give the same result: the inclusion of magnetic field enhances the quark energy loss. In particular, this effect is more pronounced when the quark is moving transverse to the magnetic field rather than parallel, consistently with the findings of the drag force and jet quenching parameter.
