118 Chapter 4: Fluctuations in Jet Tomography involves integrals that probe momentum scales that are certainly nonpertur- bative. Therefore it will be important to study the irreducible uncertainty as- sociated with the different maximum α$_{S}$ cutoff prescriptions commonly used. Further, improved numerical techniques will have to be devised to bypass the approximations employed here to incorporate essential path length fluc- tuations. Nevertheless qualitatively different high momentum behaviors are predicted for π 0 suppression at the$_{Lhc}$ from the BDMPS-based ASW models and the GLV radiative and DGLV radiative convolved with elastic loss models: for the former R$_{AA}$ ( p$_{T}$ ) is approximately flat in p$_{T}$ ; for the latter it increases significantly with p$_{T}$ . From an experimental perspective, direct measurement of D spectra would be valuable to separate the different bottom and charm jet quark dynamics that is at present convoluted in the electron spectra.
