With the vertex corrections and the NLO Wilson coefficients included, the branching ratios of the considered decays are $Br(B^+\\to J/\\Psi K_1(1270)^+)=1.76^{+0.65}_{-0.69}\\times10^{-3}, Br(B^+\\to J/\\Psi K_1(1400)^+)=7.03^{+2.70}_{-2.52}\\times10^{-4}$, and $Br(B^0\\to J/\\Psi K_1(1270)^0)=(1.63^{+0.60}_{-0.64})\\times10^{-3}$ with the mixing angle $\\theta_{K_1}=33^\\circ$, which can agree well with the data or the present experimental upper limit within errors. So we support the opinion that $\\"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.00524","kind":"arxiv","version":2},"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"}
