One of the interesting observable effects is the difference in production rates between the two CP conjugate polarized $t\\bar t$ states.","authors_text":"Darwin Chang, Ivan Phillips, Wai-Yee Keung","cross_cats":[],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"1992-09-23T07:19:46Z","title":"CP violation in top pair production at an e^+e^- collider"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/9209267","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:ce8ad0b45398391d93b9bbc43ef5d0cb8a77b7875eff57cd9727c17156ff468c","target":"record","created_at":"2026-07-04T14:29:26Z","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":"b0cf8eba51d594311fd96e0ef5fa3f2eeb4854f60a6afc6895909afc50a74344","cross_cats_sorted":[],"license":"","primary_cat":"hep-ph","submitted_at":"1992-09-23T07:19:46Z","title_canon_sha256":"78cf760efb09e0fe7ea71e57c95ebdbe15792cfeeff5b8a198a73f6ea9c2533b"},"schema_version":"1.0","source":{"id":"hep-ph/9209267","kind":"arxiv","version":1}},"canonical_sha256":"e34668d6358e99ad06d45b5120e383e053e538eef631b1e45952b77c836f2fc8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e34668d6358e99ad06d45b5120e383e053e538eef631b1e45952b77c836f2fc8","first_computed_at":"2026-07-04T14:29:26.574634Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:29:26.574634Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/CXB/rytylmysdrhwGm6s/x4zTjSL/4FSi9jq3MxOn/96K7u26ee3ck86h+nKxEUteCWwh9i9o4ApVrZR7gBAA==","signature_status":"signed_v1","signed_at":"2026-07-04T14:29:26.575028Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/9209267","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ce8ad0b45398391d93b9bbc43ef5d0cb8a77b7875eff57cd9727c17156ff468c","sha256:63f16f69ff82c9f28c3b1accea5b1c5ef8ed77f469adba2723d869ea07429ec8"],"state_sha256":"e54e75296318297ca4bde5dcb6aee0fd25de8e79336e07129d6a9692a67bef52"}
