The gauge ensembles are generated with M\\\"obius domain-wall fermions, and the overlap/domain-wall reweighting is applied. We find that the $U(1)_A$ susceptibility evaluated from the spectrum of overlap-Dirac eigenvalues is strongly suppressed in the chiral limit. We also study its volume dependence.","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":"2018-12-17T05:52:15Z","title":"Axial U(1) symmetry and Dirac spectra in high-temperature phase of $N_f=2$ lattice QCD"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.06621","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:fca0f9c114e6cdce07d5ffa8fa356140bd6bb080853c0a9bd14562dbc715108a","target":"record","created_at":"2026-07-05T01:17:36Z","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":"44d1124ec62af46b02b0fdb235bccc86f85f31926e9aa589f3d1cdbb60513321","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2018-12-17T05:52:15Z","title_canon_sha256":"f4fd865b515c6e42d61252f363be9a9d74447f787e4626528017d084783f3d0a"},"schema_version":"1.0","source":{"id":"1812.06621","kind":"arxiv","version":1}},"canonical_sha256":"927877a07974845a6e153e00d54c2cfe66af2645fb477dba0b2e22fd1a3c874d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"927877a07974845a6e153e00d54c2cfe66af2645fb477dba0b2e22fd1a3c874d","first_computed_at":"2026-07-05T01:17:36.981827Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:17:36.981827Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7oBbBj1lO+O41wczCgZ0D5adT6OP6G/uNdAi3EaldSjs3OC3BOCKKuMlgPGT69wNNoZt3ZYe3uw3V1HtKDPqAA==","signature_status":"signed_v1","signed_at":"2026-07-05T01:17:36.982227Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.06621","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fca0f9c114e6cdce07d5ffa8fa356140bd6bb080853c0a9bd14562dbc715108a","sha256:38ddbfb932aa3f6f1f3ee5fb12ae5d6d3d5b0b098981b0041e7302135022c3dc"],"state_sha256":"7f3beb4e35abe6c699b665688a1ea9416b6aea1bd8fd90f4f5bf4538d7f71032"}
