We observe that the nuclear effects encoded in both most recent global fits of nuclear parton densities at next-to-leading order (nCTEQ15 and EPPS16) provide a good overall description of the LHC data. We interpret this as a hint that these are the dominant ones. In turn, we perform a Bayesian-reweighting analysis for each particle data sampl","authors_text":"Aleksander Kusina, Hua-Sheng Shao, Ingo Schienbein, Jean-Philippe Lansberg","cross_cats":["hep-ex","nucl-ex","nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-12-19T16:17:07Z","title":"Gluon Shadowing in Heavy-Flavor Production at the LHC"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.07024","kind":"arxiv","version":2},"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":"sha256:30a63f471dda01a01071911e000986098e34efabac3f2f2f54ade2d22e1e8288","target":"record","created_at":"2026-05-18T00:09:00Z","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":"c71731941b67d690ada694f6a009002e0904eaba0e9d0322c3bda26632576681","cross_cats_sorted":["hep-ex","nucl-ex","nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-12-19T16:17:07Z","title_canon_sha256":"ea97a020ef1544dc95bce513a87b0c572447488fe1ee2256f1dbe2e7fe25c7c9"},"schema_version":"1.0","source":{"id":"1712.07024","kind":"arxiv","version":2}},"canonical_sha256":"f4b56c293cd602fab1e71b5695f3c84d00f8521856778e9bf0e5c1f808097cf5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f4b56c293cd602fab1e71b5695f3c84d00f8521856778e9bf0e5c1f808097cf5","first_computed_at":"2026-05-18T00:09:00.251531Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:00.251531Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PIRlEN3Wh6RwngnUxIyOBH5Q29AEIga6DgOAGf3sIfXZN/I5tcry42KnolWWaoP7fGlqqvpJKeNYLAnUZT0kCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:00.252132Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.07024","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:30a63f471dda01a01071911e000986098e34efabac3f2f2f54ade2d22e1e8288","sha256:979a1e2197fd421fcf2729aac8b5fcb241a0fc617f66167a6887248b1837b048"],"state_sha256":"04c0ffeade6ce15912727b6c15af95b6e3139bc7c64f759a2e4cdb5dab7994f7"}
