In particular, we show how an analysis of bundle gerbes on groups covered by SU(N) permits to determine the spectrum of symmetric branes in the boundary version of the WZW model with such groups as the target. We also describe a simple relation between the open string amplitudes in the WZW models based on simply connected groups and in their simple-current orbifolds.","authors_text":"Krzysztof Gawedzki, Nuno Reis","cross_cats":["math-ph","math.MP"],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2002-05-22T21:15:52Z","title":"WZW branes and gerbes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0205233","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:ceae9bcc44a229662326803187274b6ed76abd6faa1e3a11b821fdc8442a0e8b","target":"record","created_at":"2026-07-04T16:34:46Z","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":"0448efb26a5a09c1ce01d247e1c9139e0749178fa826baf6b1f4e787e4480693","cross_cats_sorted":["math-ph","math.MP"],"license":"","primary_cat":"hep-th","submitted_at":"2002-05-22T21:15:52Z","title_canon_sha256":"257ff19c1759cc32ff364f249f14992f4bff12f60e31a66a2ce4565adaab2d8a"},"schema_version":"1.0","source":{"id":"hep-th/0205233","kind":"arxiv","version":1}},"canonical_sha256":"d4da5fc9165447845cb8aa83d1d2d4d200dae6825d8833216db7541ac8b94037","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d4da5fc9165447845cb8aa83d1d2d4d200dae6825d8833216db7541ac8b94037","first_computed_at":"2026-07-04T16:34:46.331771Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:34:46.331771Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fEgGgkQ9RqWMlpGS7NSLPSMSmLP6z/PENXMz2hAZ4uvCHB312cxpnynzNdpXO67nF4rpbu77cnzd6KIchWDiBw==","signature_status":"signed_v1","signed_at":"2026-07-04T16:34:46.332226Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0205233","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ceae9bcc44a229662326803187274b6ed76abd6faa1e3a11b821fdc8442a0e8b","sha256:f5beed021444c60e3aef488f0a63f66122bf33e9e811983c0f631a5347696193"],"state_sha256":"191307ea2df73845a567d6579115a938d6e69926edb79057b650665cd60341b1"}
