The suppression is thus a clear, albeit indirect, indication for the presence of a QGP. The Upsilon(1S) ground state suppression is essentially due to reduced feed-down, collisional damping and gluodissociation, whereas screening prevails for the suppression of the excited states.","authors_text":"Felix Nendzig, Georg Wolschin","cross_cats":["nucl-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2012-10-31T15:31:50Z","title":"Upsilon suppression in PbPb collisions at the LHC"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1210.8366","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":"sha256:9ca83db74b8d653bfb589dabcd4d2389ebc199b07b180cf7a2cf16b82c2d466b","target":"record","created_at":"2026-05-18T03:32:31Z","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":"aacc6a018e9720a2b763c757213ba4746c16455a0444a9e9b88cbcfa5a6693e7","cross_cats_sorted":["nucl-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2012-10-31T15:31:50Z","title_canon_sha256":"32aa440646cd285ddbafc6157c8123dae6712e83a360c65cb6fd893657472040"},"schema_version":"1.0","source":{"id":"1210.8366","kind":"arxiv","version":2}},"canonical_sha256":"b557436ffffdb67547a98d43f5e865a88dfa9f89052ecf3d461caca35b7e612b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b557436ffffdb67547a98d43f5e865a88dfa9f89052ecf3d461caca35b7e612b","first_computed_at":"2026-05-18T03:32:31.493123Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:32:31.493123Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"u1PdgOfxBSxA8TZ4viEDqgMjMV14DX8sXxLHIsE4J03IkIr9X33YehzMjsDP8PMoNef++vr86ycmQG/TXTr8BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:32:31.493900Z","signed_message":"canonical_sha256_bytes"},"source_id":"1210.8366","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9ca83db74b8d653bfb589dabcd4d2389ebc199b07b180cf7a2cf16b82c2d466b","sha256:08b9ab80e612e147d675494bed6a79939650cad08e5fcf2d948393645299c141"],"state_sha256":"2d0352474b4b9c29988ad9b630874fe8776142bb0b0fd6ec8c1049996c803e69"}
