These are naturally associated to Landau singularities of the first type. Focusing on the one-loop case, we give an explicit parametrization to compute such cut integrals, with which we study some of their properties and list explicit results for maximal and next-to-maximal cuts. By analyzing homology groups, we show that cut integrals associated to Landau singu","authors_text":"Claude Duhr, Einan Gardi, Ruth Britto, Samuel Abreu","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2017-02-10T13:27:23Z","title":"Cuts from residues: the one-loop case"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.03163","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:ef854db8c96e1dc8d3fdf68af3be972da53b60d3df92d310afebd4eb7ee39d01","target":"record","created_at":"2026-05-18T00:38:57Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"eb0f28877d94f70b1221159fc0fca371b3e40ce569f41fb9642ef7c1596c8f15","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2017-02-10T13:27:23Z","title_canon_sha256":"49094bca27cd18508072f2f8d58ad0e8ce6c83c462cdcae079b44e001f528e52"},"schema_version":"1.0","source":{"id":"1702.03163","kind":"arxiv","version":2}},"canonical_sha256":"b4822664cdc09513ccb008971b4635886d1cb529685f5e90f21207d8fa35d9f6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b4822664cdc09513ccb008971b4635886d1cb529685f5e90f21207d8fa35d9f6","first_computed_at":"2026-05-18T00:38:57.794728Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:38:57.794728Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nfCXYj1ZRQxjxmJKP3h/QV02i79hJ39jM68UhgIKou904cO1N1sDRq6AKNWLDIygBbz6nHkE93Q/SMzwPb9bAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:38:57.795356Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.03163","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ef854db8c96e1dc8d3fdf68af3be972da53b60d3df92d310afebd4eb7ee39d01","sha256:cfa969c1606a8ef00ae7f0b33b0304a8633f5d627a2da97dde0d56b6f1cf6162"],"state_sha256":"b9b7d22de5873ddffdb6f28be07e0f4c1945eea8b18056bdddb986e52cf7cb80"}
