For the uncompactified Type IIB superstring, this gives a manifestly Lorentz-covariant action for a self-dual five-form field strength. Upon compactification to four dimensions, the action depends on a U(1) field strength from 4D N=2 supergravity. However, unlike the standard Maxwell action, this action is manifestly invariant under the electromagnetic duality transformation which rotates $F_{mn}$ into $\\epsilon_{mnpq} F^{pq}$.","authors_text":"Nathan Berkovits","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"1996-07-09T04:23:11Z","title":"Manifest Electromagnetic Duality in Closed Superstring Field Theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/9607070","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":"sha256:180beeb8266b9b780e8474ec16160872ec40c6011ceefee922b61f891030919c","target":"record","created_at":"2026-07-04T16:02:12Z","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":"56e5bf1a29b23b66602c3d5f0bff0e9d4a937f310f0fae084eb623256953e90c","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"1996-07-09T04:23:11Z","title_canon_sha256":"ce071503802b52672ecd055335798a5a72b9ed3bd74e34b506f5774711c53a29"},"schema_version":"1.0","source":{"id":"hep-th/9607070","kind":"arxiv","version":2}},"canonical_sha256":"9595a3ae0ae37027b7802ac11379daa1c51dad4bcf0222ad6bf8d2c8f2296af4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9595a3ae0ae37027b7802ac11379daa1c51dad4bcf0222ad6bf8d2c8f2296af4","first_computed_at":"2026-07-04T16:02:12.296981Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:02:12.296981Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rTyMR7oD+tqs0vs7UtIfHkuFZIL96fLHOcP7qw4QMagkSXU+OkXNi5lZhHVcL+QU7LxXgwJVHNJI4Of3gBwQCw==","signature_status":"signed_v1","signed_at":"2026-07-04T16:02:12.297408Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/9607070","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:180beeb8266b9b780e8474ec16160872ec40c6011ceefee922b61f891030919c","sha256:dd477961da79cfc41a7bd0de4a43901acf08efb6edd5070da2f2a6d7c5e70418"],"state_sha256":"87a085886556d4244ffa3ed24b137288a6507ed9139774eba4f269089eaca84e"}
