The observation of apparently stronger $J/\\psi$ suppression at forward rapidity compared to that at midrapidity, so called $J/\\psi$ puzzle at RHIC, can well be explained by the competition between the two production mechanisms. At LHC, however, the rapidity dependence of the $J/\\psi$ production is dominated by the regeneration process.", "revisions": [ { "version": "v1", "updated": "2009-07-16T00:52:14.000Z" } ], "analyses": { "subjects": [ "24.85.+p", "12.38.Mh", "25.75.-q" ], "keywords": [ "rapidity dependence", "heavy ion collisions", "dimensional transport equation", "regeneration process", "initial production" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0954-3899/37/7/075110", "journal": "Journal of Physics G Nuclear Physics", "year": 2010, "month": "Jul", "volume": 37, "number": 7, "pages": "075110" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 825865, "adsabs": "2010JPhG...37g5110L" } } }
