We show that such couplings can be directly probed at the LHC through the parton subprocess $c(\\bar c)g \\to t (\\bar t)A^0$, where the pseudoscalar $A^0$ subsequently decays into $t \\bar c$ or ${\\bar t} c$, giving rise to the intriguing final state of like sign top quark pairs. After demanding $\\ell^\\pm\\ell^\\pm$, missing energy and two $b$-jets, the major background turns out to be $q\\bar q' \\to Wt \\bar t$, which can be partially suppressed by jet counti"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/9702260","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
