Such twin theories are classified and shown to originate as truncations of a common theory with more supersymmetry. Moreover, we discuss the possible gaugings and scalar potentials of twin theories. This allows to pinpoint to which extent these structures are determined by the purely bosonic structure of the underlying Kac-Moody algebras and where supersymmetry comes to plays its role. As an example, we analyze the gaugings of the six-dimensional N=(0,1) and N=(2,1)","authors_text":"Diederik Roest, Henning Samtleben","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2009-04-08T14:03:37Z","title":"Twin Supergravities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0904.1344","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:ae5b6cc71f4eff3645e62bdc27090ae1d9427def436dfcd08858abf96bdea238","target":"record","created_at":"2026-07-04T15:46:26Z","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":"b68a6456fb48eceaea100d7b9c8b40a4550c2e1e58a26f703246d210ba601ec2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2009-04-08T14:03:37Z","title_canon_sha256":"bae9412766963f2acbe1e4553891dbd6ef999acb08a2882410c49dc5126de03a"},"schema_version":"1.0","source":{"id":"0904.1344","kind":"arxiv","version":2}},"canonical_sha256":"75f414cb64f2069dec04dc1a931aa9fdac4895967f3b1840d795cc7ba2b66758","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"75f414cb64f2069dec04dc1a931aa9fdac4895967f3b1840d795cc7ba2b66758","first_computed_at":"2026-07-04T15:46:26.769268Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:46:26.769268Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wv4JU1GO7f+/2phq/72I8BdZ8C+JiAQj/U2/HVemntyGyKonADPq39LMr3jFTgGlqvq+zF45K+/XwxIAeAPqCQ==","signature_status":"signed_v1","signed_at":"2026-07-04T15:46:26.769650Z","signed_message":"canonical_sha256_bytes"},"source_id":"0904.1344","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ae5b6cc71f4eff3645e62bdc27090ae1d9427def436dfcd08858abf96bdea238","sha256:41af52f012b1b511adbf3bcebe88d21b344664b6597a1525dea9df29d071299d"],"state_sha256":"c891ef9a37a1e08e86376463297df22e4343476ae914c14afb70ea61fa57e07e"}
