The complete set of dimension six operators involving two top (or anti-top) quarks is introduced and the connection with all possible t- or s-channel particle exchanges is established. Only in the former case, same and opposite sign top pair production can be related. We find that while current Tevatron data disfavor t-channel models, other production mechanisms are viable and can be tested at the LHC.","authors_text":"Celine Degrande, Christophe Grojean, Fabio Maltoni, Geraldine Servant, Jean-Marc Gerard","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-04-10T20:29:32Z","title":"An effective approach to same sign top pair production at the LHC and the forward-backward asymmetry at the Tevatron"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1104.1798","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":"sha256:9236cf9eea7e3619b39977651dad40de373d4240494859c05680c26f1d5f5631","target":"record","created_at":"2026-05-18T02:22:10Z","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":"cd961ef5b4bf98a79b347edc620b9992c3dcecd8a70a52f0044d69db50dd1214","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-04-10T20:29:32Z","title_canon_sha256":"f4dadac2f905d21b4e42fd2e771934172bf313bc4639a972a43eae2624c21eb7"},"schema_version":"1.0","source":{"id":"1104.1798","kind":"arxiv","version":2}},"canonical_sha256":"5a2f13aebee21c67abf2541df0a269bd11e9be0aeea5154e593fb45da9d9d244","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5a2f13aebee21c67abf2541df0a269bd11e9be0aeea5154e593fb45da9d9d244","first_computed_at":"2026-05-18T02:22:10.156546Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:22:10.156546Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8UUCHiiUw9e7c/S2wi9sgTOwliNKO1odkjiIkbLeHxVEDrGbrSCzUSNkIsrHfotXb347s4Zu2wVmlBTlXoPnBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:22:10.157147Z","signed_message":"canonical_sha256_bytes"},"source_id":"1104.1798","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9236cf9eea7e3619b39977651dad40de373d4240494859c05680c26f1d5f5631","sha256:0264808dbbb609ca99ec95cb133957c8beec0bf19d6a342f8fad402163dd2de1"],"state_sha256":"f53c3feaf006e9e2eafda565d6c589b98bfef70c49657443e8225f0aa2dd9089"}
