As in the previous works for the $J/\\psi$ and $\\eta_c$, in-medium effects are incorporated through the changes of gluon condensates. Twist-2 terms for the $^3 P_0 (\\chi_{c0})$ and $^3 P_1 (\\chi_{c1})$ are also included for the first time. The results show that larger mass shifts and width broadenings take place as compared to the $S$-wave states. As the critical change take place near $T_c$, related measurements can reveal critical phenomenon in QCD.", "revisions": [ { "version": "v2", "updated": "2009-01-10T07:52:42.000Z" } ], "analyses": { "subjects": [ "24.85.+p", "11.55.Hx", "14.40.Gx", "12.38.Mh" ], "keywords": [ "qcd sum rules", "p-wave charmonia", "in-medium modification", "hot gluonic matter", "larger mass shifts" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review C", "year": 2009, "month": "Jan", "volume": 79, "number": 1, "pages": "014907" }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "inspire": 792753, "adsabs": "2009PhRvC..79a4907S" } } }
