In NLO analysis we find that the hard Pomeron behavior gives a good description of $F_{L}$ and $F^{c}_{k}$ (k = 2,L) at small x values. We conclude that a direct relation between $F_{L}/F^{c}_{2}$ would provide useful information on how to measure longitudinal structure function at high $Q^{2}$ values. Having checked that this model gives a good description of the data, when compared with other models.","authors_text":"B.Rezaei, G.R.Boroun","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-02-02T09:39:24Z","title":"Longitudinal Structure Function $F_{L}$ from Charm Structure Function $F^{c}_{2}$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1402.0163","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:cd06f7f191d0f18a9c5911e55e0eaaa8021e63a9173f7062f096da02886b0f7b","target":"record","created_at":"2026-05-18T01:44:53Z","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":"213364c9bac6b393c0bcd947888363c9dc486b8ac0eda4e72e260298233c59fe","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2014-02-02T09:39:24Z","title_canon_sha256":"c70072a984b9040c8558d3274906beae2ef7be49039906222c209dbc52362456"},"schema_version":"1.0","source":{"id":"1402.0163","kind":"arxiv","version":1}},"canonical_sha256":"c48724bb66295d3afdeeefb96277140dce90bb2b0cee7d5f269eff7bbe4899ab","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c48724bb66295d3afdeeefb96277140dce90bb2b0cee7d5f269eff7bbe4899ab","first_computed_at":"2026-05-18T01:44:53.656164Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:44:53.656164Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ow8GuaRC/iU8fS0A8wD2S+3dqGc/9T+Zci7gl66K6rsJ9zWnnr7iLFxbKcv9o4VzQjslvthKWY7jVTmzT+b1Aw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:44:53.656612Z","signed_message":"canonical_sha256_bytes"},"source_id":"1402.0163","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cd06f7f191d0f18a9c5911e55e0eaaa8021e63a9173f7062f096da02886b0f7b","sha256:f43451e2c9c4da453d7db9c798be45302eadae707a9b549130f67b37b84f32f5"],"state_sha256":"ac4d7c117bddb8e7f47f40f2e3ffdf8a8e0d1046d641154c63c312d377af4d22"}
