I will describe the ingredients of this approach and how it can achieve this accuracy. Results for quark mass ratios, m_c/m_s and m_b/m_c, can also be determined to 1% from lattice QCD, allowing accuracy for the heavy quark masses to be leveraged into the light quark sector. I will discuss the prospects for, and importance of, improving results in future calculations.","authors_text":"Christine Davies","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2013-12-05T14:19:54Z","title":"Precise Determination of the Charm Quark Mass"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1312.1556","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":"sha256:8675037d1db329c40420b3d4e16bebbc4a368bd6def6b84cc6afdd02b353b377","target":"record","created_at":"2026-05-18T03:05:26Z","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":"660addc191ea3988bbb4aaec1aecefe580dad1c2bf9a0ee395b62af37f6b032e","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2013-12-05T14:19:54Z","title_canon_sha256":"02d1bb5d4f462dc36c736bf7432c6fce6b74107c31b54b0f1b86ad5fafac46bb"},"schema_version":"1.0","source":{"id":"1312.1556","kind":"arxiv","version":1}},"canonical_sha256":"e86fa7a46cc8dfde454af6e4e949cc79c42c71ee359ca4a8508bbd9ed6023c05","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e86fa7a46cc8dfde454af6e4e949cc79c42c71ee359ca4a8508bbd9ed6023c05","first_computed_at":"2026-05-18T03:05:26.917463Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:05:26.917463Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pnEks1RD8wrJOMJKv/awSQQ7HmlTDEtKQaQkXdgmkBVzCLEM/Dxx4OMDbiLgLPZQ7xMes+gPByx0SSKcJS+XCw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:05:26.917998Z","signed_message":"canonical_sha256_bytes"},"source_id":"1312.1556","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8675037d1db329c40420b3d4e16bebbc4a368bd6def6b84cc6afdd02b353b377","sha256:96523db59f28123a452e6b3792cfe8ede05d3774a2169ff8f07202e5ff6249b7"],"state_sha256":"35b0ff672ec3f4dc3c5e137b4828566fc42f90d89b76b37d24584b66a2d40378"}
