ρ$_{Q}$ is given by the initial transverse ⃗ x production distribution times the quench- ing factor from that position in direction φ with final momentum p$_{T}$ . The case shown is for a p$_{T}$ = 15 GeV jet produced initially at ( x, 0) and moving in the direction φ = 0 along the positive x axis. The quenching is determined by the participant bulk matter along its path ρ$_{QGP}$ ( x + vt, 0 , t ), and varies with x because the local path length L = L ( x, 0 , 0) changes according to Eq. (4.3).
