These are the so-called bosonic electroweak two-loop corrections, where \"bosonic\" refers to diagrams without closed fermion loops. Together with the corresponding results for the $Z$-pole asymmetries $A_l, A_b$, which have been presented earlier, this completes the theoretical description of $Z$-boson precision observables at full two-loop precision within the Standard Model. The calculation has been achieved through a combination of different methods: (a) numer","authors_text":"Ayres Freitas, Ievgen Dubovyk, Janusz Gluza, Johann Usovitsch, Tord Riemann","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-04-26T18:33:56Z","title":"Complete electroweak two-loop corrections to Z boson production and decay"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.10236","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":"sha256:0627ff2fc77bce8ac0c595ed7c5e212b9c701d643d93952c41d5c7a37cdd582f","target":"record","created_at":"2026-05-18T00:12:17Z","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":"b9bbb4716d1dea84e030d93ecb2d76ebfb661f8194ee6636fe57e000e3fb8215","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-04-26T18:33:56Z","title_canon_sha256":"c551f7552f20bea1ea2c717baea08002afb4af52e9b6f023119be0866f50e12a"},"schema_version":"1.0","source":{"id":"1804.10236","kind":"arxiv","version":1}},"canonical_sha256":"bbdc6216bb6cf75a7aac59de3d528d6e60525e762ce4104fcdbf2c27344269e0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bbdc6216bb6cf75a7aac59de3d528d6e60525e762ce4104fcdbf2c27344269e0","first_computed_at":"2026-05-18T00:12:17.282987Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:12:17.282987Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FBmJG0dGY3Uvw/wkft2FO2IQCUV2SFVE6Fx1f+C02osjY9PNj7t2FSjg0Fe6SAqCt09x1I4r6Sw/2ZqitRt9Aw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:12:17.283743Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.10236","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0627ff2fc77bce8ac0c595ed7c5e212b9c701d643d93952c41d5c7a37cdd582f","sha256:f9d38eee959cf4c9b51977fe895a2fe41b62b298624a209439008103260ef917"],"state_sha256":"2eb7552432f2a9d4025d79b3695ee9021c32797f8a6be82af6601c4439682375"}
