Two descriptions are shown to give similar matrix elements in most channels after renormalizing high momentum components. Although the range of the $\\Lambda N$ interaction is different in two potentials, the $\\Lambda$ single-particle potential in nuclear matter is very similar. The $\\Sigma$-nucleus and $\\Xi$-nucleus potentials are also found to be similar. These predictions are to be confronted with forthcoming experimental data.", "revisions": [ { "version": "v1", "updated": "2009-12-22T07:20:07.000Z" } ], "analyses": { "subjects": [ "21.65.-f", "21.30.Fe", "13.75.Ev" ], "keywords": [ "chiral effective field theory", "low-momentum equivalent interactions", "quark model", "hyperon-nucleon interactions", "comparative study" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review C", "year": 2010, "month": "Jan", "volume": 81, "number": 1, "pages": "014003" }, "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 840960, "adsabs": "2010PhRvC..81a4003K" } } }
