We show that this recent observation finds a quantitative explanation in a model which relates the suppression mechanism to the local energy density, whose value is higher in Pb-Pb collisions than in any other system studied previously. The sensitivity of the phenomenon to small changes in the energy density could be suggestive of quark-gluon plasma formation.","authors_text":"Jean-Paul Blaizot, Jean-Yves Ollitrault","cross_cats":[],"headline":"","license":"","primary_cat":"hep-ph","submitted_at":"1996-06-10T12:51:56Z","title":"J/Psi Suppression in Pb-Pb Collisions: A Hint of Quark-Gluon Plasma Production?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-ph/9606289","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:b57eb066eade0d4f45cfd9a1ef1b0a1fc723f03db62334c7c0fd910499fc1512","target":"record","created_at":"2026-07-04T15:45:45Z","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":"ddaf4cd990db5eaf461c9704c8713fa6f59099b10fb298c7d293b2aba6ae6b66","cross_cats_sorted":[],"license":"","primary_cat":"hep-ph","submitted_at":"1996-06-10T12:51:56Z","title_canon_sha256":"5ce46204b7301089588a98d22afee427381526b3f98abbf899e4a36b53a7b57e"},"schema_version":"1.0","source":{"id":"hep-ph/9606289","kind":"arxiv","version":1}},"canonical_sha256":"16255e57c7650466b6a31c95d93e975b7c4f6cc0060d7519a3f854b313648dd7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"16255e57c7650466b6a31c95d93e975b7c4f6cc0060d7519a3f854b313648dd7","first_computed_at":"2026-07-04T15:45:45.666795Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:45:45.666795Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VDYGWiM2hp6zRaxytJzmgCaps3lm/AiPPwOr3cLjDipGQjXYSzZRwXmF2t2O1E7FXEnvHY6sShfDG1PPluGUCA==","signature_status":"signed_v1","signed_at":"2026-07-04T15:45:45.667205Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-ph/9606289","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b57eb066eade0d4f45cfd9a1ef1b0a1fc723f03db62334c7c0fd910499fc1512","sha256:3a0a860a5f1900e822c0e5b67e623691e6503aabbf327a51694b6d5cf2ced5fc"],"state_sha256":"c31f44b04520a778204fd78cc8d2e87ce017f8f6d390a0ca3b49973f8d062d2a"}
