摘要

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 N = 4 supersymmetric Yang-Mills plasma. The quark is considered moving transverse and parallel to B. 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 B. In addition, we find that. has a more important effect in the transverse case than for the parallel.
