Firstly, we adopt the improved LCSR approach to deal with the $B\\to D$ TFF $f^{+}(q^2)$ up to twist-4 accuracy. Due to the elimination of the most uncertain twist-3 contribution and the large suppression of the twist-4 contribution, the obtained LCSR shall provide us a good platform for testing the $D$-meson leading-twist DA. For the purpose, we suggest a new model for the $D$-meson leading-twist DA ($\\phi_{3D}$), whose longitudinal behavior is dominantly determ","authors_text":"Hai-Bing Fu, Hua-Yong Han, Tao Zhong, Xing-Gang Wu, Yang Ma","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2013-09-23T08:08:20Z","title":"$V_{cb}$ from the semileptonic decay $B\\to D \\ell \\bar{\\nu}_{\\ell}$ and the properties of the $D$ meson distribution amplitude"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.5723","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":"sha256:0185481e556e86f202e31e45c31f326936a78de19b63f9174e34db3d52c8336c","target":"record","created_at":"2026-05-18T02:51:56Z","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":"fe9a196de5e1b84d4a2abcd77aaca493ffbd6bcd531a3be700b846aee358ee27","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2013-09-23T08:08:20Z","title_canon_sha256":"331dbcda09b3c4d4d152320dc84104d7518aaa756bf289f62fee2a01f04233eb"},"schema_version":"1.0","source":{"id":"1309.5723","kind":"arxiv","version":4}},"canonical_sha256":"71eb7907c77aea503c83bcd294d36a9d4f226ea31a5b3e3425e7fc2c57274843","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"71eb7907c77aea503c83bcd294d36a9d4f226ea31a5b3e3425e7fc2c57274843","first_computed_at":"2026-05-18T02:51:56.968241Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:51:56.968241Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/ruzvX/e69u34QXXxXytXuGjSGH/hSw91GwniClnUWNY850gR6gVsZXLtDAWovR4PgQDM6r/7PLWQjCCaw7sAw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:51:56.968773Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.5723","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0185481e556e86f202e31e45c31f326936a78de19b63f9174e34db3d52c8336c","sha256:1c70ced67a2eb2950e6353e1b7528c8c42cdbe401ebdb2428983672341f174d4"],"state_sha256":"df11a59627e8989f7b3cc6c8bd145c4bcc21cd540909e172d1b264a007a73a74"}
