We study the following new physics models: (1) exotic gluon $G^\\prime$, (2) extra $Z^\\prime$ boson with flavor-conserving interaction, (3) extra $Z^\\prime$ with flavor-violating $u$-$t$-$Z^\\prime$ interaction, (4) extra $W^\\prime$ with flavor-violating $d$-$t$-$W^\\prime$ interaction, and (5) extra scalars $S$ and $S^\\pm$ with flavor-violating $u$-$t$-$S$ and $d$-$t$-$S^\\pm$ interaction"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1003.3461","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"}
