The latter is studied at the LHC to put exclusion limits on a fourth generation of heavy fermions. Therefore also a precise knowledge of the electroweak(EW) next-to-leading-order(NLO) corrections is important. The corrections due to the fourth generation are positive and large for a light Higgs boson, positive but relatively small around the $\\bar{t}-t$ threshold and start to become negative for a Higgs boson mass around $M_H = 450 GeV$","authors_text":"Christian Sturm, Giampiero Passarino, Sandro Uccirati","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-08-09T19:50:48Z","title":"Complete Electroweak Corrections to Higgs production in a Standard Model with four generations at the LHC"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1108.2025","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":"sha256:72429ae7f498d94a69d43407512a39c4931831e42465af10a6d9a1752ce2735b","target":"record","created_at":"2026-05-18T02:00:59Z","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":"d199c363dc0494935d7c1e2adbadc408b67a95d248a7b1cabb6b82dd3419a0d7","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-08-09T19:50:48Z","title_canon_sha256":"58269ffe12ed1ec68b00e3b38d55e3a296a0dd397e25a32b0b3e901debef79f3"},"schema_version":"1.0","source":{"id":"1108.2025","kind":"arxiv","version":1}},"canonical_sha256":"7a2c6a27147a0e8f9abd6e383745083cf0b1882245f3518030d296120999284b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7a2c6a27147a0e8f9abd6e383745083cf0b1882245f3518030d296120999284b","first_computed_at":"2026-05-18T02:00:59.653570Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:00:59.653570Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"45XQx66GRX7Vx/zQtgOZ945D8DPf3pghv5W1EdW+AGzn20vYLLqJyoGt8ahLKFYtiKxMkVYpolljOXgEI0gZCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:00:59.653990Z","signed_message":"canonical_sha256_bytes"},"source_id":"1108.2025","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:72429ae7f498d94a69d43407512a39c4931831e42465af10a6d9a1752ce2735b","sha256:4a315cf958d3a97656c2707acf992162452ed37b7702f6b3dafc4caac45a2b7f"],"state_sha256":"f938a188eeca4f61498038d054a9815d99c23cfdf0f3d81bd34d37ad2452662a"}
