We find that, by detecting a fast and forward neutron in the final state, an almost on-shell $\\bar{K}$ is guaranteed, which is essential to make a bound state with two nucleons from ${}^{3} \\text{He}$. Then, this almost on-shell $\\bar{K}$ can bring a signal of the $\\bar{K} N N$ bound state in the $\\Lambda p$ invariant-mass spectrum, although it inevitably brings a kinematic peak above the $\\bar{K} N N$ threshold as well. As a consequence, we pred"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.06781","kind":"arxiv","version":1},"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"}
