Taking $^{20}$Ne as an example, we attempt to directly probe its internal $\\alpha$-cluster structure, by comparing experimentally measured observables in collisions at relativistic energies from density distributions of $^{20}$Ne with and without $\\alpha$-cluster structure. Since the two density distributions give the same nucleus size and deformation, they lead to similar mid-rapidity observables. However, the $\\alpha$-cluster structure may considerably reduce t","authors_text":"Chunjian Zhang, Hai-Cheng Wang, Jiangyong Jia, Jun Xu, Lu-Meng Liu, Song-Jie Li, Xu-Guang Huang, Zhong-Zhou Ren","cross_cats":["hep-ex","nucl-ex"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"nucl-th","submitted_at":"2025-02-12T01:44:04Z","title":"Directly probing existence of $\\alpha$-cluster structure in $^{20}$Ne by relativistic heavy-ion collisions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.08057","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":"sha256:1f3e08822d0aa2788cfb92797da74faf2e153a392ee54ba9667da6f87b017b3e","target":"record","created_at":"2026-07-05T10:18:13Z","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":"2816b65805cd11669ed4014ccf297c7c6fc5a454f053eca87727edf624d43d2e","cross_cats_sorted":["hep-ex","nucl-ex"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"nucl-th","submitted_at":"2025-02-12T01:44:04Z","title_canon_sha256":"c4513b137216d64cc1d4bb253e3d078f11398383627a9b0f65a06e8d03485d05"},"schema_version":"1.0","source":{"id":"2502.08057","kind":"arxiv","version":2}},"canonical_sha256":"c47ad80802d8c63724f12be1dc7d8fb27f3637753c27f5eb01a44ad9aa3069ac","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c47ad80802d8c63724f12be1dc7d8fb27f3637753c27f5eb01a44ad9aa3069ac","first_computed_at":"2026-07-05T10:18:13.541051Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:18:13.541051Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"i4Xox7TYn5scdAJzAbmpsPh43Ut2GYmauVYIBwYkOwBNTQSiJcVHtoYHgM+CKNYxgZ/11518TfP5tbdy7z0GDw==","signature_status":"signed_v1","signed_at":"2026-07-05T10:18:13.541728Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.08057","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1f3e08822d0aa2788cfb92797da74faf2e153a392ee54ba9667da6f87b017b3e","sha256:4ea63c2d5f17b331f2c60defcbf6a8ceb19ae08902270aca36a9d3f90376c920"],"state_sha256":"58f58ec4aca46f37d7f1fd98f04a28145cf8f21812258bd76ef459326cbf8ade"}
