Drag force in strongly coupled supersymmetric Yang–Mills plasma in a magnetic field

Abstract

Applying AdS/CFT correspondence, we study the effect of a constant magnetic field on the drag force associated with a heavy quark moving through a strongly-coupled supersymmetric Yang–Mills plasma. The quark is considered moving transverse and parallel to . It is shown that for transverse case, the drag force is linearly dependent on in all regions, while for parallel case, the drag force increases monotonously with increasing and also reveals a linear behavior in the regions of strong . In addition, we find that has a more important effect in the transverse case than for the parallel.
