Using separable potentials for $\\bar{K}N-\\pi\\Sigma$ interaction, we have calculated the transition probability for the $(Y_{K})_{I=0}+N\\rightarrow\\pi\\Sigma{N}$ reaction. The possibility to observe the trace of $K^{-}pp$ quasi-bound state in the $\\pi\\Sigma{N}$ mass spectra was studied. Various types of chiral based and phenomenological potentials are used to describe the $\\bar{K}N-\\pi\\Sigma$ interaction. It was shown that not only we can see the signature of the $K^{"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.07340","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"}
