CMS is well suited to measure quarkonia decays to muons given the muon identification and charged particle tracking capability. We report here prompt, non-prompt J/\\psi, and \\Upsilon\\ production measured by the CMS experiment in pp collisions at \\sqrt{s}=7 TeV. In addition, the J/\\psi\\ and \\Upsilon\\ production in PbPb at \\sqrt{s_{NN}}=2.76 TeV and pp collisions at the same per nucleon energy are measured and compared. Prompt and non-prompt J/\\psi\\ contributions are separated for the first time in heavy-ion collisions, as is the ground from the excited states in the \\Upsilon\\ family. Suppression in PbPb at \\sqrt{s_{NN}}=2.76 TeV is quantified for prompt J/\\psi, B->J/\\psi, and \\Upsilon(1S), as well as the relative suppression of \\Upsilon(2S+3S) compared to \\Upsilon(1S).", "revisions": [ { "version": "v1", "updated": "2011-08-25T13:24:06.000Z" } ], "analyses": { "keywords": [ "cms experiment", "pbpb collisions", "quarkonia measurements", "pp collisions", "heavy-ion collisions" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0954-3899/38/12/124033", "journal": "Journal of Physics G Nuclear Physics", "year": 2011, "month": "Dec", "volume": 38, "number": 12, "pages": 124033 }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 925053, "adsabs": "2011JPhG...38l4033S" } } }
