The result not only gives striking support to the two-pomeron description of small-x behaviour, but gives a rather clean test of perturbative QCD itself. When x is very small, or Q^2 is very large, the proton's gluon distribution function is significantly larger than is commonly believed. Perturbative evolution is invalid below Q^2\\approx 5 GeV^2.", "revisions": [ { "version": "v3", "updated": "2002-04-09T13:16:48.000Z" } ], "analyses": { "keywords": [ "regge theory", "perturbative qcd", "protons gluon distribution function", "perturbative evolution", "small-x behaviour" ], "tags": [ "journal article" ], "note": { "typesetting": "Plain TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 567515 } } }
