The Wigner distribution, as a quasi-distribution function, provides the most general one-parton information in a hadron. Combining the polarization configurations, unpolarized, longitudinal polarized or transversal polarized, of the quark and the proton, we can define 16 independent Wigner distributions at leading twist. We calculate all these Wigner distributions for the $u$ quark and the $d$ quark respectively. In our calculation, both the scalar and the axial-vector spectators are included, and the Melosh-Wigner ","authors_text":"Bo-Qiang Ma, Tianbo Liu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2015-01-30T07:52:30Z","title":"Quark Wigner distributions in a light-cone spectator model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1501.07690","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:f2b7befda68370bab60d2a5ce00bf9ff274edb0d29a51e90a033ad1263fe3c07","target":"record","created_at":"2026-05-18T01:41:05Z","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":"ca4d4a40ef7d9f3f3bd14e50849bb4c8a327811aae502156de26bfbea2bad3f9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2015-01-30T07:52:30Z","title_canon_sha256":"d7dec03f5d4002cdee9e878a39ba2cff940a39b46b9933aae69ddb2ec7b141ce"},"schema_version":"1.0","source":{"id":"1501.07690","kind":"arxiv","version":1}},"canonical_sha256":"967fd11782c5ac30364f1211b6ee74cceb8450eeeaa921124eaa9dbabaac78ac","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"967fd11782c5ac30364f1211b6ee74cceb8450eeeaa921124eaa9dbabaac78ac","first_computed_at":"2026-05-18T01:41:05.729839Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:41:05.729839Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"EnkX3wFPtv3d/w1oPAI4IVgGLB3XvdrjSYdX+GyuKu2US/9o0Anrv+TF4i3+pM/D/PUqVw62IPqKmpDRYIUbDw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:41:05.730481Z","signed_message":"canonical_sha256_bytes"},"source_id":"1501.07690","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f2b7befda68370bab60d2a5ce00bf9ff274edb0d29a51e90a033ad1263fe3c07","sha256:b347f0f07ca97dce11b37af17b01d01362fa40fe6d8df9ccb2d1b2a04c21c01b"],"state_sha256":"e5ca65ad39328ba904a456f821a695a9f4d99cc80b5f496e56c5802838bdedda"}
