Holographic light-quark energy loss in a spinning plasma

Abstract 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. The results show that light quarks thermalize more readily in a hot environment. For parallel propagation, a counter-propagating configuration facilitates thermalization, whereas a co-propagating configuration suppresses it. For transverse propagation, increasing the magnitude of the rotational motion promotes thermalization. In addition, the instantaneous energy loss increases along the trajectory of the endpoint.
