This corresponds to the variation after projection, reversing the order of semiclassical quantization of $1/N_c$ expansion. The method, however, is considered to be suited to the study of weakly interacting kaon-nucleon systems including loosely $\\bar{K}N$ bound states such as $\\Lambda(1405)$. We have found a bound state with binding energy of order ten MeV, consistent with the observed state. We also discuss the $\\bar{K}N$ interaction and find that it consists of an attraction in the middle range and a repulsion in the short range.", "revisions": [ { "version": "v1", "updated": "2016-05-04T10:03:34.000Z" } ], "analyses": { "keywords": [ "skyrme model", "interaction", "study kaon-nucleon systems", "bound state approach", "short range" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1455815 } } }
