The CF is constrained by centrality selection based on particle multiplicity in a reference subevent, and contributes to observables measured in another subevent. Using a Glauber-based independent source model, we study the influence of CF on several distributions of multiplicity $N$ and eccentricities $\\epsilon_n$: $p(N)$, $p(\\epsilon_n)$, $p(\\epsilon_n,\\epsilon_m)$ and $p(N,\\epsilon_n)$, where the effects of CF is quantified using multi-particle","authors_text":"Jiangyong Jia, Mingliang Zhou","cross_cats":["hep-ph","nucl-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-03-05T18:09:22Z","title":"Centrality fluctuations in heavy-ion collisions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.01812","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":"sha256:1af1d09c71fe151d546eb0835b1efc9a4a75704004b811503f783434c5d23610","target":"record","created_at":"2026-05-18T00:02:35Z","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":"8c1962de6bacc80fca5905dae4b407257224e150d94ac2600d4d682b59b114a7","cross_cats_sorted":["hep-ph","nucl-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-03-05T18:09:22Z","title_canon_sha256":"c07ff393998092b81d2eb7b90acf36b6208f714c65b410478d97f903e0da1b0c"},"schema_version":"1.0","source":{"id":"1803.01812","kind":"arxiv","version":2}},"canonical_sha256":"43da7630a19a08fb1e06d757d34f44f05a7b351bed2716415611fba2d78b43cf","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"43da7630a19a08fb1e06d757d34f44f05a7b351bed2716415611fba2d78b43cf","first_computed_at":"2026-05-18T00:02:35.500513Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:02:35.500513Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EZeG/oBgW8j6NZovYCXCQ6s3Qta2yxGmUNhKgTmOb4IIxxCYRaM3AXzN7BMul5jninAQxoNcHkOnOqxThIoBBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:02:35.501058Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.01812","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1af1d09c71fe151d546eb0835b1efc9a4a75704004b811503f783434c5d23610","sha256:07b2583018d4eb1a0228c50e09c44758d097979c2f8af933f4cfb22d1c3b537f"],"state_sha256":"96c52454fd38fc98a67a8aaab02efba7c892a9fd9dcfef7957b351885d8c16ca"}
