Then we calculate the decay widths of different modes. The decay width of the S-wave modes b_1 \\pi, f_1\\pi increases quickly as the hybrid meson mass and decay momentum increase. But for the low mass hybrid meson around 1.6 GeV, the P-wave decay mode \\rho \\pi is very important and its width is around 180 MeV, while the widths of \\eta \\pi and \\eta^","authors_text":"Hua-Xing Chen, Peng-Zhi Huang, Shi-Lin Zhu, Zi-Xing Cai","cross_cats":["hep-ex","nucl-ex","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2010-10-19T16:45:47Z","title":"The Decay Properties of the 1^{-+} Hybrid State"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1010.3974","kind":"arxiv","version":4},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5e815f1d7fc10153d5622ffb74270a540be32b4c9f020e1303e89d467d1b6afe","target":"record","created_at":"2026-05-18T02:23:45Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"4f797bf0f04b65a3bf2ccd8a9ec93337ef831be42ddb3cc599d0aa37370d95c7","cross_cats_sorted":["hep-ex","nucl-ex","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2010-10-19T16:45:47Z","title_canon_sha256":"71fe9e95d1ceba8a3974dabf496c8e0d396ebbb2845ee562b4975eca76f66f77"},"schema_version":"1.0","source":{"id":"1010.3974","kind":"arxiv","version":4}},"canonical_sha256":"7200aca2b43573d0bc2ab80a8849834d08013de8820509d98b1d1255228fbfd4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7200aca2b43573d0bc2ab80a8849834d08013de8820509d98b1d1255228fbfd4","first_computed_at":"2026-05-18T02:23:45.274531Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:23:45.274531Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ollriGGtyEd0v2IbX/5t/m95zPyogLAzZT/tUcj8UoTr51D/shiGFXXpmI15dUg0H7j/RkRCtCaFg1QBOvPTBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:23:45.275192Z","signed_message":"canonical_sha256_bytes"},"source_id":"1010.3974","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5e815f1d7fc10153d5622ffb74270a540be32b4c9f020e1303e89d467d1b6afe","sha256:25cd087e2026c8a9af859a2cb6e87568058e0280c1d257574a236beba49924b3"],"state_sha256":"d67dbab84f24096a6283dbc20f1bf55e6ac5ffef0d6412d6b7744efcc5003fa6"}
