The constraints on the parameter space are obtained by considering $t \\to b \\tau^+ \\nu$ data, lepton flavor universality tests in the kaon sector, bounds on $B \\to K^{(*)} \\bar \\nu \\nu$, bound on the lepton flavor violating decay $B \\to K \\mu \\tau$, and measurements of $b \\to c \\mu^- \\bar\\nu$ decays. The presence of such vector leptoquark could be exposed in precise measurements of $t \\to b \\tau \\nu$ and $B \\to K^{(*)} \\bar \\nu \\nu$ "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.06024","kind":"arxiv","version":4},"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"}
