Light quark energy loss in the flavor-dependent systems from holography

Le résumé fourni par la source

Using the holographic model of finite-endpoint-momentum shooting string approach, we study the instantaneous energy loss of light quarks for the flavor-dependent systems with $N_f = 0$, $N_f = 2$, and $N_f = 2+1$ in the Einstein-Maxwell-dilaton (EMD) framework. In particular, we investigate for the first time the impact of the flavor content of the strongly coupled QGP medium on the instantaneous energy loss of light quarks. It turns out that the instantaneous energy loss of light quarks is smallest for $N_f = 0$, 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 endpoint due to rising temperature or chemical potential.
