For the first time, a four-particle cumulant method is used to extract the second Fourier coefficient of the azimuthal distribution ($v_2$) of D$^0$ mesons as a function of event centrality and the D$^0$ transverse momentum. The ratios of the four-particle $v_2$ values to previously measured two-particle cumulant results provide direct experimental access to event-by-event fluctuations of charm quark azimuthal anisotropies.","authors_text":"CMS Collaboration","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ex","submitted_at":"2021-12-22T21:41:06Z","title":"Probing charm quark dynamics via multiparticle correlations in PbPb collisions at $\\sqrt{s_\\mathrm{NN}} =$ 5.02 TeV"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2112.12236","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":"sha256:651e6d5da12478501d63c879b243c1356359a02a5b243aa3aacd685ddb66e526","target":"record","created_at":"2026-07-05T04:37:56Z","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":"d6c51341a7c1741e6b63b264a312e94033275492164fbf37cc5e6f38c91d7d63","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-ex","submitted_at":"2021-12-22T21:41:06Z","title_canon_sha256":"84c720e45e19dab141475e584fcf2f4832f4ecb833d10183cf82b5cf1ec0ceaf"},"schema_version":"1.0","source":{"id":"2112.12236","kind":"arxiv","version":2}},"canonical_sha256":"8a5848cb847291616b84bd74305819a2818b7c68df8b2d4fb9e943fbff447a71","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8a5848cb847291616b84bd74305819a2818b7c68df8b2d4fb9e943fbff447a71","first_computed_at":"2026-07-05T04:37:56.882922Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:37:56.882922Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"MMQbS6+SpwFIS3uMCTAQffnPvOtecwD53OCEDRDZV1iK2yOJ4HriCi2Bm943mm61edA1Wg90kZURZWenLPxJCg==","signature_status":"signed_v1","signed_at":"2026-07-05T04:37:56.883391Z","signed_message":"canonical_sha256_bytes"},"source_id":"2112.12236","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:651e6d5da12478501d63c879b243c1356359a02a5b243aa3aacd685ddb66e526","sha256:f92f141c67306a9826c3df60caab1ee44ba16ec93767c5cc058894286db60eb1"],"state_sha256":"f369455c477d2adf0b8c668fc32b127d642df728f77ffc780b166c8146edd5b5"}
