Holographic light-quark energy loss in a spinning plasma

In this work, we investigate light-quark energy loss in a strongly coupled plasma described by a spinning black-brane background obtained from the large-black-hole limit of the Myers–Perry geometry. The parameter $a$ characterizes the boost/rotation of the dual fluid in this holographic setup and is related to the angular velocity in the corresponding limit. We employ two complementary probes, the falling-string and shooting-string descriptions, to compute the stopping distance and the instantaneous energy loss of a light quark moving either transverse or parallel to the rotation axis. We find that increasing the temperature or the parameter $a$ reduces the stopping distance and enhances the instantaneous energy loss. The effect of $a$ is more pronounced for transverse motion than for motion along the rotation axis, indicating an anisotropic energy-loss pattern induced by the spinning/boosted background. These results are consistent with earlier holographic studies of jet quenching and heavy-quark dynamics in rotating plasmas.
