We work in the framework of the collinear QCD approach where generalized gluon distributions factorize from perturbatively calculable coefficient functions. We include both $O(m_c)$ terms in the coefficient functions and $O(M_D)$ mass term contributions in the heavy meson distribution amplitudes. We show that this process may be accessed at future electron-ion colliders.","authors_text":"B.Pire, J.Wagner, L.Szymanowski","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2021-04-11T07:31:37Z","title":"Charged current electroproduction of a charmed meson at an electron-ion collider"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2104.04944","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:fd2f29224befbd271e0269a82e20b42da46bbcb5752dc775b59c4cdc5822b670","target":"record","created_at":"2026-07-05T03:32:00Z","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":"6c266da2958293d474a14ac0b98d5c57cee5af3284d3420aad60aa239f3c538d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2021-04-11T07:31:37Z","title_canon_sha256":"16c94d16d79429b4963ac07f06c5e54412f5cd4403dc1c76185737996620cf8a"},"schema_version":"1.0","source":{"id":"2104.04944","kind":"arxiv","version":1}},"canonical_sha256":"cb6939ac930d459cf352654c3c342d5c66823bd1d637ac89771f1b45e191d492","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cb6939ac930d459cf352654c3c342d5c66823bd1d637ac89771f1b45e191d492","first_computed_at":"2026-07-05T03:32:00.047646Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:32:00.047646Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XLidMKnOfMQp0RlVTixMaza+X83BEm0JXYWKcXpL8BP/YjqRWRo8yhZtkIorW83GvSw8jOEfk0aWdT9XSzUyAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T03:32:00.048280Z","signed_message":"canonical_sha256_bytes"},"source_id":"2104.04944","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fd2f29224befbd271e0269a82e20b42da46bbcb5752dc775b59c4cdc5822b670","sha256:525e54553d036f19612d20c2135bf869be3cf5289b87c03015b4e4cdba624a99"],"state_sha256":"7786fc6a91800d1de10822f2bc1ae82b8602f808406bfa4f5156de71881d80e9"}
