For the Sigma(1620) we consider the $\\bar{K}N$, $\\pi\\Sigma$, and $\\pi\\Lambda$ (I=1) multiquark interpolating fields. The calculated mass from those multiquark states is about 1.592 GeV. For the Lambda(1405) we first show the result using the\n $\\pi^+\\Sigma^- + \\pi^0\\Sigma^0 + \\pi^-\\Sigma^+$ (I=0) multiquark interpolating field, and compare the calculated mass to that of our previous result using the"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"nucl-th/9808044","kind":"arxiv","version":2},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
