We obtain the value $M_X=\\left(5.57\\pm0.12 \\right) \\,\\rm{GeV}$, which is consistent with the experimental data. The present prediction favors assigning the $X(5568)$ to be the scalar tetraquark state.", "revisions": [ { "version": "v1", "updated": "2016-02-28T13:13:05.000Z" } ], "analyses": { "keywords": [ "scalar tetraquark state", "qcd sum rules", "diquark-antidiquark model", "diquark-antidiquark type tetraquark state", "scalar-diquark-scalar-antidiquark type current" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160208711W", "inspire": 1424857 } } }
