We use an $N_f=2+1+1$ ensemble of maximally twisted mass fermions with a clover improvement. The lattice has a spatial extent of 3~fm, the lattice spacing is 0.093~fm, and the pion mass is $260$~MeV. The matrix elements are obtained with a source-sink time separation of 1.12~fm to control contamination from excited states. The calculation is based on the quasi-PDF approach and employs three va","authors_text":"Andreas Metz, Aurora Scapellato, Fernanda Steffens, Krzysztof Cichy, Martha Constantinou, Shohini Bhattacharya","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2021-11-01T16:01:22Z","title":"First study of twist-3 PDFs for the proton from lattice QCD"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2111.01056","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:a2a478a1c1546cd0c0dc6be051c451b44bdeb7643b2900bc79d10b1dea0bae30","target":"record","created_at":"2026-07-05T03:27:53Z","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":"2e01d723b64721c36de3fb390a08694fd1cb5d8d272c8d4a81d1adb1c0dae9a8","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2021-11-01T16:01:22Z","title_canon_sha256":"35f5b2d9a477fcf4e6df5c41831d8527a2b2b0823d19c5aa7139fd79e88591c9"},"schema_version":"1.0","source":{"id":"2111.01056","kind":"arxiv","version":1}},"canonical_sha256":"90e8e4dd3142388cb7a2debb961e37d01b80f85dd5b1bf9ec0758a15e0699080","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"90e8e4dd3142388cb7a2debb961e37d01b80f85dd5b1bf9ec0758a15e0699080","first_computed_at":"2026-07-05T03:27:53.135733Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:27:53.135733Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"E7DH5acg66GKH9356TmpScX7lxQmoe6HNMLxWZWftXLcScoH1OmTpx/f+49dsKQpqO6o0CZFZ7S3KjHZuTNDDw==","signature_status":"signed_v1","signed_at":"2026-07-05T03:27:53.136166Z","signed_message":"canonical_sha256_bytes"},"source_id":"2111.01056","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a2a478a1c1546cd0c0dc6be051c451b44bdeb7643b2900bc79d10b1dea0bae30","sha256:35aef61bcc1f0639f9c6e5643dec2f4ce0724247eb2c93aac8a24ff7598079c5"],"state_sha256":"d22f3ed977270f7aaf5148995dce7c1b802c8a7730d9363b8c3414e8c2497e1e"}
