This process is important for quarkonium production when the transverse momentum is much greater than the quark mass. Resummation of logarithms of the ratio of these two scales requires the evolution equations for double parton fragmentation functions (DPFF). In this paper we complete the one-loop evaluation of the anomalous dimensions for the DPFF. We also consider possible mixing between the DPFF and single parton power suppressed gluon fragmentation and show that such effects are sub-leading.", "revisions": [ { "version": "v1", "updated": "2013-01-16T20:47:07.000Z" } ], "analyses": { "subjects": [ "13.87.Fh" ], "keywords": [ "double parton fragmentation functions", "anomalous dimensions", "parton power suppressed gluon fragmentation", "single parton power suppressed gluon" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2013, "month": "Apr", "volume": 87, "number": 7, "pages": "074022" }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1211207, "adsabs": "2013PhRvD..87g4022F" } } }
