In the Randall-Sundrum model, the decay t-prime -> t Z has a large branching ratio that could be detected at the Large Hadron Collider (LHC). We also look at the two-Higgs doublet models I, II and III, and note that, in the latter, the branching ratio of t-prime -> t H, where H is a Higgs scalar or pseudoscalar, is huge and we discuss detection at the LHC.","authors_text":"Erin De Pree, Gardner Marshall, Marc Sher","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2009-10-16T15:24:51Z","title":"Fourth Generation t-prime in Extensions of the Standard Model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0910.3141","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:cdd481192721b1c556d3c842cff4dbaa8d8cc44da9d66d2d151af1a79989bec7","target":"record","created_at":"2026-05-18T02:11:15Z","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":"667fffff1ddb14ada5ab9a1ed23005c5fb42fcb5e159aeffe0ca2e96ff7b2199","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2009-10-16T15:24:51Z","title_canon_sha256":"bd9643672b1250fd9ee9bc54f1eb9fde0f185ee6ad2c6fbfbd54ef93312da4cd"},"schema_version":"1.0","source":{"id":"0910.3141","kind":"arxiv","version":1}},"canonical_sha256":"61fa7b98ef7952b9bced4ebbc271b19a0a8102c83fdd1e8b5f089bb27d54548c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"61fa7b98ef7952b9bced4ebbc271b19a0a8102c83fdd1e8b5f089bb27d54548c","first_computed_at":"2026-05-18T02:11:15.091204Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:11:15.091204Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"O3bybGy/DtjuscG5981NGP78MSgL7Uvk1U5jvH1YtJ5kDbTgPcr/zJXqYY28z0L0zSPWiH7+q9jVwbJLTpEmDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:11:15.092061Z","signed_message":"canonical_sha256_bytes"},"source_id":"0910.3141","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cdd481192721b1c556d3c842cff4dbaa8d8cc44da9d66d2d151af1a79989bec7","sha256:fd8678f43d4d31f4cca9fc9115fa871568805ee034e6c84c394a6324503a445f"],"state_sha256":"2123e6cb82a8544046075f9ca2fdeee3751f95a81bd993f9b81e4c978a195f3c"}
