114 Chapter 4: Fluctuations in Jet Tomography partonic production spectrum, dN/dp$_{T}$ ∝ 1 /p n ( p$_{T}$ ) T (see Appendix B); thus R$_{AA}$ increases with p$_{T}$ . On the other hand, the ASW models mimic the small normalization of the Rhic data by highly suppressing their jets; as discussed in the subsequent paragraphs, the significant quenching leads to a loss of in- formation on the details of the energy loss process, flattening the results. The two ASW models represented in Fig. 4.12 used EKRT-type medium density scaling [402] making the Lhc medium ∼ 7 times more dense than at $_{Rhic}$. Figure 4.11: Radiative DGLV and TG and BT elastic partonic fractional energy loss as implemented in WHDG [152] at Lhc momenta for all jet species at fixed L = 5 fm and (a) dN$_{g}$/dy = 1750 and (b) dN$_{g}$/dy = 2900 ; the former density comes from the Phobos extrapolation [87, 403], the latter from the KLN model of the color glass condensate (CGC) [400]. Δ E/E exhibits asymptotic behavior for both energy loss channels as given by the analytic pocket formulae Eq. (4.9) and Eq. (4.10). (a) (b)
