We use both the tensor current $\\bar\\psi\\sigma_{\\mu\\nu}\\psi$ and the derivative current $\\bar{\\psi}\\overleftrightarrow{D}_\\mu\\gamma_5\\psi$ as interpolating currents to calculate the partial decay width of the $b_1\\pi$ decay mode. Comparing the sum rules obtained by using different currents, we obtain $\\Gamma(\\pi_1\\to b_1\\pi)$ = 8--23, 32--86 and 52--151\\,MeV for $m_{1^{-+}}$ = 1.6, 1.8 and 2.0\\,GeV respectively, which favour the results from the flux tube models "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1608.03028","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"}
