These yields are proportional to the number of binary nucleon-nucleon interactions, which is characteristically different due to the presence of the large neutron skin in $^{96}_{40}$Zr. This provides an independent opportunity to measure the difference between the neutron skin of $^{96}_{44}$Ru and $^{96}_{40}$Zr, which can provide an important constraint on the Equation of State of cold neutron-rich matter.","authors_text":"Govert Nijs, Wilke van der Schee, Yen-Jie Lee, Yi Chen","cross_cats":["hep-ph","nucl-ex"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"nucl-th","submitted_at":"2023-07-21T18:10:21Z","title":"Hard probes in isobar collisions as a probe of the neutron skin"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2307.11836","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:e4a2ce7844c82a11f3c6bd322a22426c58e3c631065e812bb8cabc3b6bd82cbb","target":"record","created_at":"2026-07-05T06:33:35Z","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":"294771da0bed05dfcff904ca69e6c5aeb773b0a5096d92788404cad6f5ba1b8c","cross_cats_sorted":["hep-ph","nucl-ex"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"nucl-th","submitted_at":"2023-07-21T18:10:21Z","title_canon_sha256":"9a5f3c0c7c51f7de8a3a829df71691f0923c0c4af78cc008537add6b8b6712af"},"schema_version":"1.0","source":{"id":"2307.11836","kind":"arxiv","version":1}},"canonical_sha256":"fbdbfd363bec6a2c36bcfdd10fd10eb83b1757c9f17b6de5f35a96dfe970de7c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fbdbfd363bec6a2c36bcfdd10fd10eb83b1757c9f17b6de5f35a96dfe970de7c","first_computed_at":"2026-07-05T06:33:35.503274Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:33:35.503274Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"la+GeLyJHiurHwQVTgcEU2PjY90LZy812bG9lBboiukIg/7FrfgIXHPwXZN6yHYaBvbn3DrHlLNZl+ueZ1+wAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T06:33:35.503710Z","signed_message":"canonical_sha256_bytes"},"source_id":"2307.11836","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e4a2ce7844c82a11f3c6bd322a22426c58e3c631065e812bb8cabc3b6bd82cbb","sha256:af53c73ebaf4b732d74f3132edbff4c94a64abfadc71d2387dcc49aa2ff439fe"],"state_sha256":"2d7d64cf8c1136058dedb1e18c2b629077dd62b2c848c49a2a9ba134adf9181c"}
