To render this solution consistent with current algebra results, the up quark must receive an alternative mass contribution that conserves CP symmetry. Such a contribution could be provided by QCD through non-perturbative topological effects, including instantons. In this talk, we present the first direct lattice computation of this topological mass contribution, using gauge configurations generated by the Extended Twisted Mass collaboration. We use the Iwasaki gauge action, Wilson twisted mass fermions","authors_text":"Bartosz Kostrzewa, Carsten Urbach, Constantia Alexandrou, Ferenc Pittler, Jacob Finkenrath, Karl Jansen, Lena Funcke","cross_cats":["hep-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-lat","submitted_at":"2021-10-30T16:52:55Z","title":"Lattice QCD results for the topological up-quark mass contribution: too small to rescue the $m_u=0$ solution to the strong CP problem"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2111.00288","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":"sha256:591bad5033df114ee5eb34f381e7f22cfe019ce2e68d873632b65bb7ad85c043","target":"record","created_at":"2026-07-05T03:36:40Z","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":"e0b44dc0b823efc6d896f407420d0914322e067c3ceb4ab7c18c32d26a956f45","cross_cats_sorted":["hep-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-lat","submitted_at":"2021-10-30T16:52:55Z","title_canon_sha256":"3d599c33efcba8a9c1b007aa6ee28b1ec0844f78ad60f29deadde69cbc5695f0"},"schema_version":"1.0","source":{"id":"2111.00288","kind":"arxiv","version":2}},"canonical_sha256":"6f3ce60b623f0095cce241bfe5d27bf99e41dc3e4ee419d32fc2c8ae5494f662","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6f3ce60b623f0095cce241bfe5d27bf99e41dc3e4ee419d32fc2c8ae5494f662","first_computed_at":"2026-07-05T03:36:40.778853Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:36:40.778853Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"i9T71Kw+xFN1ARPYP3zTeoayyxMrFTWus0T0iSoCM8IAat9QUUyJrXvDg50m1aKWmEbE3KRod6tSbyIG/724CA==","signature_status":"signed_v1","signed_at":"2026-07-05T03:36:40.779448Z","signed_message":"canonical_sha256_bytes"},"source_id":"2111.00288","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:591bad5033df114ee5eb34f381e7f22cfe019ce2e68d873632b65bb7ad85c043","sha256:4afb6010a0fad9407098251bdb2ed64b9dfaed0f4c94964b1606a55006a7ffb2"],"state_sha256":"d43ec12bfdfc48986c4d6467a1e899ca7dc859d5dc4c2b781de4995eebe39cf0"}
