The interpolated current of the hybrid is chosen as $g\\bar q\\gamma_{\\alpha}G_{\\alpha\\mu}^aT^ah_{\\it v}(x)$, $g\\bar q\\gamma_{\\alpha}\\gamma_{5}G_{\\alpha\\mu}^aT^ah_{\\it v}(x)$ and $g\\bar q\\sigma_{\\mu\\alpha}G_{\\alpha\\mu}^aT^ah_{\\it v}(x)$. Some strong couplings and decay widths of the heavy-light hybrids to $B(D)\\pi$ are calculated by using the QCD sum rules. The mass of $0^{++}$ hybrid with gluon in TM($1^{--}$) or TE($1^{+-}$) mode is found similar, while their decay widths are differe"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/9906494","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"}
