From our calculations, we find that the decay branching ratios for color allowed tree-dominated decays $B\\to a_{2}^{0}\\pi^{+}$ and $B\\to a_{2}^{-}\\pi^{+}$ modes are of order $10^{-6}$ and $10^{-5}$, respectively. While other color suppressed tree-dominated decays have very small branching ratios. In general, the branching ratios of most decays are in the range of $10^{-5}$ to $10^{-8}$, which are bigger by one or two orders of magnit","authors_text":"Cai-Dian Lu, Xin Yu, Zhi-Tian Zou","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2012-03-19T14:33:10Z","title":"Nonleptonic two-body charmless B decays involving a tensor meson in the Perturbative QCD Approach"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1203.4120","kind":"arxiv","version":1},"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:a6516cd8203ce9a61beceeb8e8321997c39753f6cdfaa1a9e02aeefd25709b3a","target":"record","created_at":"2026-05-18T03:22:51Z","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":"77841ec487041cff596410f9ed0dde76861638119bbf5a7a6578809e7915af37","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2012-03-19T14:33:10Z","title_canon_sha256":"fcc26213c17caf27b928b7af6ab6336a9ad0d71dd653ad93b0b61ffe4230fa3e"},"schema_version":"1.0","source":{"id":"1203.4120","kind":"arxiv","version":1}},"canonical_sha256":"3acb5ca74b3dd254f60e5051ec0e47c29de56c44844549ec1b7a7dee8f214afe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3acb5ca74b3dd254f60e5051ec0e47c29de56c44844549ec1b7a7dee8f214afe","first_computed_at":"2026-05-18T03:22:51.424875Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:22:51.424875Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PyPDYQp1QsI9Q52hLie5tbarLe9F1o1hL63FI7eIR8wotu2yI2D8iqMDKySiy+2WlWRnGvi8Pb79GutCu+myAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:22:51.425379Z","signed_message":"canonical_sha256_bytes"},"source_id":"1203.4120","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a6516cd8203ce9a61beceeb8e8321997c39753f6cdfaa1a9e02aeefd25709b3a","sha256:ad11c88ee0b0b06a10835bc790f739bb1d51b238009944b5a2c4e69e81bc6805"],"state_sha256":"04f29bfb90c495b5e90ee59617e8a64e06fa846be0fe2efc77046df99803ce44"}
