To this end, we utilize lattice QCD data for the vector current for two mass-degenerate quark flavours and extract all longitudinal and transverse form factors of the underlying vertex for two off-shell kinematics. The momentum dependence of the form factors is compared to the solution of the inhomogeneous Bethe-Salpeter equation for the vertex in the rainbow-ladder approximation. Differences but also similarities are seen between our lattice and the truncated continuum results.","authors_text":"Andr\\'e Sternbeck, Milena Leutnant","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2018-12-28T17:50:51Z","title":"Quark-photon vertex from lattice QCD in Landau gauge"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.11131","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":"sha256:0cbdc9a92f20134661c488deb7f8be881181db3097f720dee79c7073bd4ebfaf","target":"record","created_at":"2026-05-17T23:47:50Z","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":"a666761d795a470c8caf948a701f992939a5299ccde39bb9a25cc4724ff253c9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-lat","submitted_at":"2018-12-28T17:50:51Z","title_canon_sha256":"2619ac71f24fe6816cd09d6f71c56e52bd91fb52fd46bdd4eb6641e2df19886b"},"schema_version":"1.0","source":{"id":"1812.11131","kind":"arxiv","version":1}},"canonical_sha256":"f61849355d08e9ba790063ce99ed21f31da2a011493b8811f0641e13d3901984","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f61849355d08e9ba790063ce99ed21f31da2a011493b8811f0641e13d3901984","first_computed_at":"2026-05-17T23:47:50.739961Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:47:50.739961Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FjNtGz+Y1qjxiwf7e3IwRSXatQeau+f4O2IIB2EcqIeHoLNNhy44/LJc4oPNIiOSbnzLSaD1I9a2qPBe2wRXCA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:47:50.740417Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.11131","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0cbdc9a92f20134661c488deb7f8be881181db3097f720dee79c7073bd4ebfaf","sha256:71b2c88073907e9d28f20c8f7eab6ecea3ea47875be29090c758ea8b9350d80a"],"state_sha256":"ef30d4b823af086c55442b076890d974e1c8689b42c4e03a601ab62931f19454"}
