We contribute towards the understanding of the non-manifest on-shell transformations in (2,2) superspace by analyzing the extended on-shell supersymmetry of such models and find that a rather general ansatz for the additional supersymmetry (not involving central charge transformations) leads to hyperk\\\"ahler geometry. We give non-trivial examples of these models.","authors_text":"Malin G\\\"oteman, Martin Rocek, Ulf Lindstr\\\"om","cross_cats":["math.DG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-07-19T18:33:06Z","title":"Semichiral Sigma Models with 4D Hyperkaehler Geometry"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1207.4753","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":"sha256:9a81cf4ec6b89e050e24cc9da959a0df70e70f40fde03493867ac7443c59b323","target":"record","created_at":"2026-05-18T01:56:16Z","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":"0ba09575bb146e3b025d80f9723420fa6a39f49524fb21f6b3974f18cbf1930b","cross_cats_sorted":["math.DG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2012-07-19T18:33:06Z","title_canon_sha256":"10c0e5ec014ad649c93874787b4eb09e5b4bc50a1f2a3a28e4852658f9ca9ec6"},"schema_version":"1.0","source":{"id":"1207.4753","kind":"arxiv","version":1}},"canonical_sha256":"8a999e939d765c4155f15c174da1171a939fd1dfc31ca9594fac46d39cdb43a5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8a999e939d765c4155f15c174da1171a939fd1dfc31ca9594fac46d39cdb43a5","first_computed_at":"2026-05-18T01:56:16.125618Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:56:16.125618Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"nZchoI3A+kS6wb+XRn2y2mkWPnQSM2YiGH+lq5T9s9LHHcnuUk+Iitea1uG2OnqsQ9R4zgMl6+a+VoiR4dT9BA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:56:16.126375Z","signed_message":"canonical_sha256_bytes"},"source_id":"1207.4753","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9a81cf4ec6b89e050e24cc9da959a0df70e70f40fde03493867ac7443c59b323","sha256:817e96c6f21ed03e5dc78f1a98426eead193ec2708d6deca33023e48e12f1df8"],"state_sha256":"2f22f8557cf518b4280cdb7aaf54df84daf301c246f0a3b5406501a8e2daae7d"}
