In this scenario, the baryon asymmetry is generated through the $CP$-asymmetric decoupling of electroweak (EW) sphaleron-like transitions. We introduce seven $CP$-violating dimension-8 operators constructed from the Higgs doublet and the $SU(2)_L$ gauge fields and show that five of them can individually account for the observed baryon asymmetry with satisfying experimental constraints from colliders or electron ","authors_text":"Kiyoto Ogawa, Masanori Tanaka","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2026-08-06T12:20:59Z","title":"Impact of dimension-8 SMEFT operators on baryogenesis via sphaleron decoupling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2608.05950","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:d287ae3131b2b7d6e9a59641699f365f6faecc725d0667ee8a71104bc4138882","target":"record","created_at":"2026-08-07T00:54:02Z","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":"f3931afa29abf2b0221f6195714a86ae7b815fd9bb73850970af30e7d6fbd48f","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ph","submitted_at":"2026-08-06T12:20:59Z","title_canon_sha256":"83bb9416e44651e8c4f58a94395e12be41716981ad482eaf26cb9d11e2acc069"},"schema_version":"1.0","source":{"id":"2608.05950","kind":"arxiv","version":1}},"canonical_sha256":"9aa0e9987b3e843f7b1b69501efeba3e9dba92be856ee82e8950c2043a04edf8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9aa0e9987b3e843f7b1b69501efeba3e9dba92be856ee82e8950c2043a04edf8","first_computed_at":"2026-08-07T00:54:02.984388Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-07T00:54:02.984388Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QNZxNR0aVhNh/1LeBQZBh458nBWMzhhFNmWf8NBJcofYuqWZX4dJY0N48FE76YfFJiuvW3ThfXVrIrV71To7Cg==","signature_status":"signed_v1","signed_at":"2026-08-07T00:54:02.985964Z","signed_message":"canonical_sha256_bytes"},"source_id":"2608.05950","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d287ae3131b2b7d6e9a59641699f365f6faecc725d0667ee8a71104bc4138882","sha256:d45df5315a0d75e0fb3ca036bfe16ee531fd7e99e1c6b77eb91f613b39731467"],"state_sha256":"140a877b2eca74d4cd6763274835b6483b890836c1014b58a24d588e755f85ca"}
