Finite Higgs boson mass effects are taken into account via an expansion which is shown to converge quickly. We obtain analytic results for the next-to-leading order form factors which can be used to compute the cross section. The method used for the calculation of the (non-planar) master integrals is described in detail and explicit results are presented.","authors_text":"David Wellmann, Go Mishima, Joshua Davies, Matthias Steinhauser","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-11-13T19:00:12Z","title":"Double Higgs boson production at NLO in the high-energy limit: complete analytic results"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.05489","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":"sha256:47f49ffa1360b607453e88cacb368f20e508b220b7eef81d3e1fe5cfcf602b7b","target":"record","created_at":"2026-05-17T23:53:24Z","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":"44bea60fd68e4e12a67387c4cc7b5bb340a6eb905dd38d1e5a34121372e332b4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-11-13T19:00:12Z","title_canon_sha256":"22dbbe2a9c2cd23443b81e0c1f785516790eaac318e15ac10073010682ebec7d"},"schema_version":"1.0","source":{"id":"1811.05489","kind":"arxiv","version":2}},"canonical_sha256":"58495b7cd510baa9dcf1a3ff59b1f38470a8df560ed1745fc81476fc590fa2dd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"58495b7cd510baa9dcf1a3ff59b1f38470a8df560ed1745fc81476fc590fa2dd","first_computed_at":"2026-05-17T23:53:24.452331Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:53:24.452331Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"I9A3TEtO83Er95kqgDepc0rTVIC6gYHDFHFQ1oKUgHqvk2PtVaJy+KvgUcYtPHnAUny4ah0GA+g8gSumAgVWBQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:53:24.452847Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.05489","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:47f49ffa1360b607453e88cacb368f20e508b220b7eef81d3e1fe5cfcf602b7b","sha256:edfaa7db2d176ac7a2c82273f59b4327dce8206c3b285faf1b239ed43ce323e3"],"state_sha256":"0fe1a6caf6299cd1ae7450ef6ce64c9dd3c48cbd719064b5d829bb5239476a48"}
