These calculations establish an ideal fluid dynamic baseline that can be used to assess non-equilibrium features manifest in future LHC heavy-ion experiments. Contrary to earlier suggestions we find that a saturation and even decrease of the differential elliptic flow v_2(p_T) with increasing collision energy cannot be unambiguously associated with the QCD phase transition.", "revisions": [ { "version": "v2", "updated": "2008-11-28T21:58:02.000Z" } ], "analyses": { "keywords": [ "elliptic flow", "heavy-ion collisions", "lhc energies", "hydrodynamic radial", "ideal fluid dynamic baseline" ], "tags": [ "journal article" ], "publication": { "journal": "European Physical Journal C", "year": 2009, "month": "Jun", "volume": 61, "number": 4, "pages": 545 }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "inspire": 789310, "adsabs": "2009EPJC...61..545K" } } }
