The 3-point interactions are completely determined by conformal symmetry, up to a constant. We do not know of any theoretical upper bounds on this constant. Imposing current experimental constraints, we find that these interactions mediate spectacular collider signals, such as $pp -> U -> UU -> \\gamma \\gamma \\gamma \\gamma$, $\\gamma \\gamma ZZ$, $ZZZZ$, $\\gamma \\gamma l^+ l^-$, $ZZ l^+ l^-$, and $4l$, with cross sections of picobarns or larger at the Large Hadron Collider. Self-interactions may therefore provide the leading discovery prospects for unparticle physics.", "revisions": [ { "version": "v2", "updated": "2008-03-16T07:25:13.000Z" } ], "analyses": { "subjects": [ "14.80.-j", "11.25.Hf", "13.85.-t", "12.60.-i" ], "keywords": [ "collider implications", "unparticle self-interactions", "interactions mediate spectacular collider signals", "unparticle physics", "large hadron collider" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2008, "month": "Apr", "volume": 77, "number": 7, "pages": "075007" }, "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "inspire": 777162, "adsabs": "2008PhRvD..77g5007F" } } }
