We revisit an old proposal where a pseudoscalar $A^0$ has mass between $t\\bar c$ and $t\\bar t$ thresholds. With $\\rho_{tt}$ small, it evades $gg \\to A^0 \\to h^0(125)Z$ constraints, where approximate alignment also helps. We find this scenario with relatively light $A^0$ is not yet ruled out, and $cg \\to tA^0 \\to tt\\bar c$ can probe sizable $\\rho_{tc}$ at the LHC, giving access to the second me","authors_text":"Masaya Kohda, Tanmoy Modak, Wei-Shu Hou","cross_cats":["hep-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-08-01T14:20:28Z","title":"Constraining a Lighter Exotic Scalar via Same-sign Top"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.00333","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":"sha256:3bc90b75c6cd6a24dc5e1c24dc46858109533a4e2dce949edeea920c10ad18da","target":"record","created_at":"2026-05-18T00:03:15Z","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":"e81364c75f33d7b0457f43a77ba14fd5a4863bca1d1314ebc1d4de54789fd9bb","cross_cats_sorted":["hep-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-08-01T14:20:28Z","title_canon_sha256":"008add869beea1cf7714329e74c5ca9653213bd515410a6f9ee8a2d610de1d6d"},"schema_version":"1.0","source":{"id":"1808.00333","kind":"arxiv","version":2}},"canonical_sha256":"de36601cd4441614921ae78b6ec6297836f091af90ab96d41050ccca37418d01","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"de36601cd4441614921ae78b6ec6297836f091af90ab96d41050ccca37418d01","first_computed_at":"2026-05-18T00:03:15.552625Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:03:15.552625Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yZUX4zRja3qVDQNmRQHJIHLLVG6YZI/PrDXdD8yG4hju1Wdd5QwZh1RhNWwzwTTI4Uszhi0ymX1hVyw+PWUgAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:03:15.553130Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.00333","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3bc90b75c6cd6a24dc5e1c24dc46858109533a4e2dce949edeea920c10ad18da","sha256:e767fcbdda38cfdbad0a3c78d1523b4e28c9ed2cb0e09122cb2e752593d2219e"],"state_sha256":"199591106f9e9f50b3faa1ade122fd0a05a7f931468fe97e55263a6b985b82e6"}
