Using a simple string configuration, we derive a formula, $(M-m_c)^2=\\pi\\sigma L$, whose coefficient of the r.h.s. is just 1/2 of that of a light meson with two light quarks. A numerical plot is obtained for $D$ mesons of experimental data as well as several theoretical models, which shows good agreement with this formula.","authors_text":"Qi-Fang L\\\"u, Takayuki Matsuki, Yubing Dong","cross_cats":["hep-ex","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2016-11-19T14:58:14Z","title":"String point of view for heavy-light mesons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.06374","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:e16bcd0fcf638b9f4675e378be77e55cdefcd353a1952270df356c2e4da3e649","target":"record","created_at":"2026-05-18T00:47:08Z","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":"b78fb85c84782f2de1866641a369dcb5b681fc55b398f44698da5c7ad324f5df","cross_cats_sorted":["hep-ex","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2016-11-19T14:58:14Z","title_canon_sha256":"30be083930ef0d8bd67b3e4886390665cf21f4a4a691e5a66216476b8e163440"},"schema_version":"1.0","source":{"id":"1611.06374","kind":"arxiv","version":1}},"canonical_sha256":"fb3cb19389e84a40e9cbc5a2467a9b79e4335977b2b939d79c28875c04e71670","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fb3cb19389e84a40e9cbc5a2467a9b79e4335977b2b939d79c28875c04e71670","first_computed_at":"2026-05-18T00:47:08.229452Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:47:08.229452Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"thUstWLypA7AylU+pmajwkSG/fl7tSiiHmcxYmQYLY4Vq8royCcxFNHnPqmWOzxQN4AtGgfdUi9WUpiWwPo/Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:47:08.229882Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.06374","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e16bcd0fcf638b9f4675e378be77e55cdefcd353a1952270df356c2e4da3e649","sha256:48a51b4b98d6d1c979a833844537e2d07bb8a7fbf56321b1827c017e8b1f51fa"],"state_sha256":"f04cc557108cad89718c1cf4eb9fa1fdcdcfc963d10dfade3fb9b6cf1351d2d5"}
