89 Chapter 3: v$_{2}$ vs. R$_{AA}$ as a Constraint on sQGP Dynamics 3.5 Conclusions By failing to simultaneously match the R$_{AA}$ and v$_{2}$ values seen at Rhic we discounted the MPC and pure GREL models. We showed that while includ- ing medium-induced absorption reproduces the R$_{AA}$ ( φ ) phenomena, it does so at the expense of inconsistent and huge dN$_{g}$/dy . Recent parton cascade results including 2 ↔ 3 processes were claimed [141] to simultaneously fit both R$_{AA}$ ( p$_{T}$ ) and v$_{2}$ ( p$_{T}$ ). Careful examination of the paper reveals that their large v$_{2}$ comes from using huge α$_{s}$ = . 6 and gluon jets only, but the claims of consistency with R$_{AA}$ use only α$_{s}$ = . 3. In this chapter we showed that the addition of a mere 5% punch created a $_{Rhic}$-following trend. The reduction in Debye mass from the hot, dense center of the medium to the cool, diffuse edge provides just such an order of magnitude momentum change.
