In particular we find that a qualitative energy loss model gives a good description of $R_{\\rm AA}$ vs.\\ $v_2$ only when we take $\\Delta E\\sim l^3$ and a medium geometry generated by a model of the Color Glass Condensate. This same $\\Delta E\\sim l^3$ model also qualitatively describes the trigger $p_T$ dependence of $R_{\\rm AA}$ vs.\\ $I_{\\rm AA}$ data and makes novel predictions for the centrality dependence for this $R_{\\rm AA}$ vs.\\ $I_{\\rm AA}$ correlation. Current data suggests, albeit with extremely large uncertainty, that $v_2^{I_{\\rm AA}}\\gg v_2$, a correlation that is difficult to reproduce in current energy loss models.", "revisions": [ { "version": "v2", "updated": "2011-06-29T17:29:19.000Z" } ], "analyses": { "subjects": [ "25.75.-q" ], "keywords": [ "correlation", "current energy loss models", "centrality dependence", "multiple jet quenching observables", "energy loss mechanism" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review C", "year": 2011, "month": "Sep", "volume": 84, "number": 3, "pages": "034904" }, "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "inspire": 883272, "adsabs": "2011PhRvC..84c4904J" } } }
