Different equations of state, namely, a free hadron gas, a first-order phase transition and a crossover are compared. An enhancement of $v_4$ at $\\sqrt{s_{{NN}}}\\approx 6$ GeV is predicted for an EoS with a first-order phase transition. This enhanced $v_4$ flow is driven by both the enhancement of $v_2$ as ","authors_text":"Horst Stoecker, Jan Steinheimer, Yasushi Nara","cross_cats":["hep-ph","nucl-ex"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-09-12T02:57:50Z","title":"The enhancement of $v_4$ in nuclear collisions at the highest densities signals a first order phase transition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.04237","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":"sha256:580943e969bb715c3c32e9171a587cb3ba085755ab7d1bd6d01f6f4ad8cf48d4","target":"record","created_at":"2026-05-18T00:00:50Z","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":"53977c632cd31817b65da6fd58ce905b82d2611ff64ff7c04d158f347d2e433b","cross_cats_sorted":["hep-ph","nucl-ex"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2018-09-12T02:57:50Z","title_canon_sha256":"b175c0cba9fb37ca642da033faf60413b522d2ac4fa71a6f8fde8e1ea5853d46"},"schema_version":"1.0","source":{"id":"1809.04237","kind":"arxiv","version":1}},"canonical_sha256":"6e02d1e2cfef9d10132218729bbfafa534ff4ad2eea146ca46984bd684973cbe","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6e02d1e2cfef9d10132218729bbfafa534ff4ad2eea146ca46984bd684973cbe","first_computed_at":"2026-05-18T00:00:50.227638Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:00:50.227638Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7b5Kowh81w8pt+GuFHuyeJt5JDrIp8kobcJfhihKzbwHa3UCB5nOZkXEUOLx8Qcb7olYfsGJzs9w0mE7CRrJDA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:00:50.228369Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.04237","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:580943e969bb715c3c32e9171a587cb3ba085755ab7d1bd6d01f6f4ad8cf48d4","sha256:48a7270fdcae563b38979b345aaeb3c791fe9eeb54d3c05eab614f60b8880024"],"state_sha256":"e7ed491fce70d5cd126cc492d5015b6b64b7de2c9961f9abcb5ad10e5233fea1"}
