The subtractions are given as form-factor integrands whose integrals are known. The resulting subtracted amplitudes are amenable to efficient numerical integration. Our procedure is based on the universality of infrared singularities and requires a relatively limited set of subtractions, whose number grows as the number of two-loop diagrams, rather than with the number of singular regions of integration.","authors_text":"Charalampos Anastasiou, George Sterman","cross_cats":["hep-th"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"hep-ph","submitted_at":"2022-12-23T05:56:18Z","title":"Locally finite two-loop QCD amplitudes from IR universality for electroweak production"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.12162","kind":"arxiv","version":1},"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:e3eb1e6028ac9e04ffd804d52609a23a8ca6a7ee27935644e93eae3ba5930149","target":"record","created_at":"2026-07-05T06:21:57Z","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":"34d444ab18e3c31a2690a27db4787f95e0263fa6cd66e6fe02f76bb31459a8dd","cross_cats_sorted":["hep-th"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"hep-ph","submitted_at":"2022-12-23T05:56:18Z","title_canon_sha256":"79c47ba25da885b65a59693eee56376a19816dff12b5f94357b92b814d4eb23d"},"schema_version":"1.0","source":{"id":"2212.12162","kind":"arxiv","version":1}},"canonical_sha256":"8ffb74182bccfd5ebb260278e957b27d453c93e7e55a1b59bfb5fca37ecbfaf2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8ffb74182bccfd5ebb260278e957b27d453c93e7e55a1b59bfb5fca37ecbfaf2","first_computed_at":"2026-07-05T06:21:57.204007Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:21:57.204007Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TMcjNEkusdJhoJj/l5b++DN59cfgdHDklzlTx1OmNyPb3a1AzcMoKQVjertl+Hn3md7NXhETHvNuXQ5ZBF4mDA==","signature_status":"signed_v1","signed_at":"2026-07-05T06:21:57.204483Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.12162","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e3eb1e6028ac9e04ffd804d52609a23a8ca6a7ee27935644e93eae3ba5930149","sha256:f664ab79703b36007e56f1ccdf4257bc63f3178bab43ce9514fc0017e2c7cdbe"],"state_sha256":"89ced8af29d33168c269d9877b8088f22b13afcfe1962c80ba540eba0b71edd0"}
