We consider the boost-invariant cylindrically symmetric systems and the effects of the phase transition are taken into account by using a temperature dependent sound velocity inferred from the lattice simulations of QCD. We find that the transverse flow acquires the scaling form r/t within the short evolution times, 10 - 15 fm, only if the initial transverse flow originating from the pre-equilibrium collective behavior is present at the initial s","authors_text":"Mikolaj Chojnacki, Tamas Csorgo, Wojciech Florkowski","cross_cats":[],"headline":"","license":"","primary_cat":"nucl-th","submitted_at":"2004-10-07T16:47:57Z","title":"On the formation of Hubble flow in Little Bangs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"nucl-th/0410036","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":"sha256:0ddf2003b1c93aa446c9b14f306d41038b59684908eb2226e1718808d4b5408a","target":"record","created_at":"2026-07-04T16:49:43Z","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":"0c121d4a3d29928271a93f9a915ff83d69666f8830399cbe4a94b91009b37393","cross_cats_sorted":[],"license":"","primary_cat":"nucl-th","submitted_at":"2004-10-07T16:47:57Z","title_canon_sha256":"99cb7790f537a8b874bf977ec9aa318f72cbda0e6018dbefce056076c5faaa2b"},"schema_version":"1.0","source":{"id":"nucl-th/0410036","kind":"arxiv","version":1}},"canonical_sha256":"7bc9afdec55e3e72eec1d1b05b9ddacdb54f5edaa01cf905247a98df87d0a2d9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7bc9afdec55e3e72eec1d1b05b9ddacdb54f5edaa01cf905247a98df87d0a2d9","first_computed_at":"2026-07-04T16:49:43.360673Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:49:43.360673Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tTsRSkv57BhuEctFdBlZ6bK+/8IERdc64xLFt/VF6YupJOGhb6TEqlxLnc4+b/W65QwI4TXWLxUsgR2k5PP3DA==","signature_status":"signed_v1","signed_at":"2026-07-04T16:49:43.361062Z","signed_message":"canonical_sha256_bytes"},"source_id":"nucl-th/0410036","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0ddf2003b1c93aa446c9b14f306d41038b59684908eb2226e1718808d4b5408a","sha256:95ea4e25cd6ff22d655ec00a2b97c198d5016e3fa9fe83229818834d3476849e"],"state_sha256":"1aea5db1a45e093d444a71e199a0611dfad791c4cfc337e2b9a40dd0d28d2165"}
