Our gauge ensembles are generated with M\\\"obius domain-wall fermions, but the measurements such as susceptibilities are reweighted to those for the overlap fermions by using overlap/domain-wall reweighting technique. We find that the $U(1)_A$ and topological susceptibilities are strongly suppressed in the small quark mass region, which is related to the reduction of chiral-ze","authors_text":"Guido Cossu, Hidenori Fukaya, Kei Suzuki, Shoji Hashimoto (JLQCD Collaboration), Sinya Aoki, Yasumichi Aoki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2019-08-29T11:51:05Z","title":"Axial U(1) symmetry, topology, and Dirac spectra at high temperature in $N_f=2$ lattice QCD"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1908.11684","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:bc1bc0c0ed0654b069d505c9e109cf5271fb10d1ec6a47b237db27cf31ca4fdb","target":"record","created_at":"2026-07-05T01:17:24Z","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":"e37e8d616b44e40fa8a9b73c34a3bd94a25ba59a786fd20dba74b0747b4f27b9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2019-08-29T11:51:05Z","title_canon_sha256":"977171546f660908bff17a163d894b58c6c9041104f5f2e7308e4719fd6e3341"},"schema_version":"1.0","source":{"id":"1908.11684","kind":"arxiv","version":1}},"canonical_sha256":"828b3f21886d22585c07cb053b0348adfdb6feb42279cce502bea73cb16aa921","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"828b3f21886d22585c07cb053b0348adfdb6feb42279cce502bea73cb16aa921","first_computed_at":"2026-07-05T01:17:24.761554Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:17:24.761554Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Fap1f6zqIZoq87lKKyo5dJ/Yh1TSg8MKyYPm7Fo4cWTbSYHGtschKnxTv3UTFTFFwtGL7QL3WWt43H8NsFP0CQ==","signature_status":"signed_v1","signed_at":"2026-07-05T01:17:24.762042Z","signed_message":"canonical_sha256_bytes"},"source_id":"1908.11684","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bc1bc0c0ed0654b069d505c9e109cf5271fb10d1ec6a47b237db27cf31ca4fdb","sha256:b2834251deafa5e9fd5a09e58c6990dfdc8204b43293b82bba101ed9e5efd7ce"],"state_sha256":"68a3c3bea05138d60be609d431234c108818301608b4aff730a63cf4f3f758b0"}
