The complete multipole structure of photonic radiation is incorporated in a single branching kernel. The regular on-shell 2 to 3 kinematic picture is kept intact by dividing the radiative phase space into sectors, allowing for a definition of the ordering variable that is similar to QCD antenna showers. A modified version of the Sudakov veto algorithm is discussed that increases performance at the cost of the introduction of weighted events. Due to the absence of a soft singularity, the formalism for photon splitting is very simila","authors_text":"Rob Verheyen, Ronald Kleiss","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-09-13T18:06:11Z","title":"Final-state QED Multipole Radiation in Antenna Parton Showers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.04485","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:c41d769a30689e6ee9fa1078494e5e73fa5d99046b806d475319ce414eb21012","target":"record","created_at":"2026-05-18T00:25:54Z","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":"8197708a7ad1aba2b85c4c9eb3bf0ebd7c402b513c69c4e2abba948c24a5a285","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2017-09-13T18:06:11Z","title_canon_sha256":"84389c508352637a5d66e02e6ffdbe4144c76ea7dd017a6e299a96ba972abbf4"},"schema_version":"1.0","source":{"id":"1709.04485","kind":"arxiv","version":2}},"canonical_sha256":"cd97cfab44e22da0fcdbf71f9f586a9d73da8634ab92563a6955470b10932426","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cd97cfab44e22da0fcdbf71f9f586a9d73da8634ab92563a6955470b10932426","first_computed_at":"2026-05-18T00:25:54.986306Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:25:54.986306Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UB0U9BFLyhCM74OucV9Ob4abQRUkwcFl0i+irwXFuvWWHM0YlXSf1XH/dvVr0Ytw+RAJHj7lEMaNgza/P8baDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:25:54.986903Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.04485","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c41d769a30689e6ee9fa1078494e5e73fa5d99046b806d475319ce414eb21012","sha256:82a4d50f220b3e1cd0156f67f1648fbab5d053d7491dd569a63c90204baf2b93"],"state_sha256":"a130285fdecc32b708582075dcb0c144fd88925b02364452a198a63576eaf172"}
