Our results show that the interactions of $B\\bar{B}^*$, $B^*\\bar{B}^*$, $D\\bar{D}^*$ and $D^*\\bar{D}^*$ states are attractive, which consequently result in $B\\bar{B}^*$, $B^*\\bar{B}^*$, $D\\bar{D}^*$ and $D^*\\bar{D}^*$ bound states. The recent observed exotic-like hadrons of $Z_b(10610)$ and $Z_b(10650)$ are, therefore in our approach, interpreted as loosely bound states of $B\\bar{B}^*$ and $B^*\\bar{B}^*$, while X(3872) and Y(3940) are $D\\bar{D}^*$ and $D^*\\bar{D}^*$ molecule states, respectively.", "revisions": [ { "version": "v1", "updated": "2012-04-18T01:45:34.000Z" } ], "analyses": { "subjects": [ "12.39.-x", "14.40.Rt", "13.75.Lb" ], "keywords": [ "chiral quark model", "molecule states", "systematic study", "loosely bound states", "consequently result" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0954-3899/40/1/015003", "journal": "Journal of Physics G Nuclear Physics", "year": 2013, "month": "Jan", "volume": 40, "number": 1, "pages": "015003" }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1111242, "adsabs": "2013JPhG...40a5003L" } } }
