Starting from quantum kinetic equations, the stopping power of dense plasmas is investigated. Strong beam-plasma correlations which occur for highly charged beam ions and strongly coupled plasmas are considered on the level of the static screened T-matrix approximation. Furthermore, dynamic screening effects are included. This approach is used to investigate the ion charge number dependence of the stopping power. In the strong coupling region, a modification of the Z2b scaling law which follows from weak coupling theories is found. The comparison of the T-matrix results with simulation data (PIC) shows good agreement for low beam velocities.
