The QCD AM operators are converted to effective spin-flavor operators expressing instanton-induced chiral interactions. A large negative orbital AM $L_{u - d}$ arises as a ``chiral magnetic effect'' of the interaction of the quarks with the chiral mean field in the proton in the large-$N_c$ limit. It cancels part of the large positive spin AM $S_{u-d}$ and reduces the total AM $J_{u-d} = L_{u-d} + S_{u-d}$, i","authors_text":"Christian Weiss, Ho-Yeon Won, June-Young Kim","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2026-05-22T00:49:16Z","title":"Quark orbital angular momentum as a chiral magnetic effect"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.23125","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:e51c998d240110517660e841babfb8f8021e61c8f1bc6d858f478e6d2a0e4f35","target":"record","created_at":"2026-05-25T02:01:39Z","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":"7541bc58851edec522ba33fe2f7d822f7367beb0d805598db7ec2b2134010aa0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2026-05-22T00:49:16Z","title_canon_sha256":"71c322f263ad2a0e68e202848350598e064f388f2bc382ca8d338aed0e1bf3d8"},"schema_version":"1.0","source":{"id":"2605.23125","kind":"arxiv","version":1}},"canonical_sha256":"a9bfb020b79028eaa751f08af528ceddf1a6c88d76763c4095a78809fb674f55","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a9bfb020b79028eaa751f08af528ceddf1a6c88d76763c4095a78809fb674f55","first_computed_at":"2026-05-25T02:01:39.453689Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-25T02:01:39.453689Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qhGVQ6W7+S0GSOR9Ye7bYQCMnVZickDnPmq5qbqFs9sjdY7tbdWGLQ26UEXAg8dxYhSVHCyiY5wCVnOL7XmZDw==","signature_status":"signed_v1","signed_at":"2026-05-25T02:01:39.454264Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.23125","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e51c998d240110517660e841babfb8f8021e61c8f1bc6d858f478e6d2a0e4f35","sha256:719fcf666cbb83b875087d8058075586692da016a9cb6f54544fec1ab6575c73","sha256:1850207ada66d3a4d80ba646cfb27d696ff6a2acd20e6803f1afe3d671cce16b"],"state_sha256":"40c37f22a2ba9e26629d8f27bb951fc338b57bfb37efbe1fa8dd26ef33f4ef47"}
