The background metric is a T^2 fibration over a K3 base times four-dimensional Minkowski space. Depending on the choice of three-form flux different amounts of supersymmetry are preserved (N=2,1,0). For supersymmetric solutions unbroken space-time supersymmetry determines all background fields except one scalar function which is related to the dilaton. The heterotic Bianchi identity gives rise to a differential equation for the dilaton which we discuss in detail for solutions preserving an N=2 ","authors_text":"Chris Bertinato, Guangyu Guo, Katrin Becker, Yu-Chieh Chung","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2009-04-19T20:28:13Z","title":"Supersymmetry breaking, heterotic strings and fluxes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0904.2932","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":"sha256:48c79e5f15fefd9c08fa8d31893a7854547e1449b261ebe06703efd8d37ccc10","target":"record","created_at":"2026-05-18T04:24:35Z","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":"be9c9ee6405efc883f83b7a9722ac8759ef6892e83c4c2dc97546a6a49544307","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2009-04-19T20:28:13Z","title_canon_sha256":"ab7da975d597f198f3dbcce685efeeba1a789adbe672d645087b87f867ef06ac"},"schema_version":"1.0","source":{"id":"0904.2932","kind":"arxiv","version":2}},"canonical_sha256":"903d5a4b0e3d53832b436bf4f01952288bb5ebc4c7e9e104ea2a4432dd0c0ec6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"903d5a4b0e3d53832b436bf4f01952288bb5ebc4c7e9e104ea2a4432dd0c0ec6","first_computed_at":"2026-05-18T04:24:35.362322Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:24:35.362322Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m/mqG1CE6pMhcP/HzhErFIm08v5epfLJKBpBAmQqlTTP2ZfHEbhFQMOEUOLe9dhVyaXAKc0r3motlbOwQ4sVCw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:24:35.362730Z","signed_message":"canonical_sha256_bytes"},"source_id":"0904.2932","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:48c79e5f15fefd9c08fa8d31893a7854547e1449b261ebe06703efd8d37ccc10","sha256:501880d9e21aadd63b0bda269f5e4bb13a7f1e4aa3294df23ebcdca05d5b4cf0"],"state_sha256":"8361ad10d3fbacbf10eaeec9c99618e7bc8bbea2f2a14032ea3a6eb39f4c4ca2"}
