Qualitative and quantitative energy loss?

Despite the 300% systematic theoretical uncertainty associated with extracting image using current energy loss models due to the collinear approximation, and despite the uncertainties in the initial geometry and corrections due to the fluctuations in the initial overlap of a heavy ion collision, a simultaneous description of high-image image image and image is not possible with current pQCD-based energy loss models. However a good description of out-of-plane image as a function of centrality is possible. Alternatively, energy loss models based on AdS/CFT give a better qualitative description of image and non-photonic electron image as well as high-image ratios of image to image production than those based on pQCD.
