In this note, we use the KLT-formula to investigate the theorem. We have shown how the soft behavior of color ordered Yang-Mills amplitudes can be combined with KLT relation to give the soft behavior of gravity amplitudes. As a byproduct, we find two nontrivial identities of the KLT momentum kernel must hold.", "revisions": [ { "version": "v1", "updated": "2014-08-19T00:03:27.000Z" } ], "analyses": { "keywords": [ "soft graviton theorem", "klt relation", "soft behavior", "klt momentum kernel", "color ordered yang-mills amplitudes" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/JHEP11(2014)090", "journal": "Journal of High Energy Physics", "year": 2014, "month": "Nov", "volume": 2014, "pages": 90 }, "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1311496, "adsabs": "2014JHEP...11..090D" } } }
