Abstract

Using the holographic model of the finite end point momentum shooting string approach, we study the instantaneous energy loss of light quarks for the flavor-dependent systems with Nf=0, Nf=2, and Nf=2+1 in the Einstein-Maxwell-dilaton framework. In particular, we investigate for the first time the impact of the flavor content of the strongly coupled quark-gluon plasma medium on the instantaneous energy loss of light quarks. It turns out that the instantaneous energy loss of light quarks is smallest for Nf=0, and adding u(d) quarks and s quark in the system increases this energy loss. In addition, we found that the instantaneous energy loss in the strongly coupled plasma is minimal near the critical temperature, but it increases as the system moves away from the critical end point due to rising temperature or chemical potential.
