A positive value for $\\mu_s$ is obtained in the $s\\bar s$ configuration where the $uuds$ subsystem is in an orbitally excited state with $[4]_{[FS]}[22]_F[22]_S$ flavor-spin symmetry, which is likely to have the lowest energy. The configurations in which the $\\bar s$ is orbitally excited, which include the conventional $K^+\\Lambda^0$ configuration, with exception of that in which the $uuds$ component has spin 2, yield negative values for $\\mu_s$. The hidden strangeness analogues of recently proposed quark cluster models for the $\\theta^+$ pentaquark give differing signs for $\\mu_s$.", "revisions": [ { "version": "v2", "updated": "2005-07-01T07:37:27.000Z" } ], "analyses": { "subjects": [ "12.39.-x", "13.40.Em", "14.20.Dh" ], "keywords": [ "configuration", "positive strangeness magnetic moment", "hidden strangeness analogues", "quark cluster models", "complete analysis" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
