We calculate the chiral spectra of flipped SU(5) GUTs by using the spectral divisor construction. The results agree with those from the analysis of semi-local spectral covers. Our computations provide an example for the validity of the spectral divisor construction and suggest that the standard heterotic formulae are applicable to the case of F-theory on an elliptically fibered Calabi-Yau fourfold with no heterotic dual.","authors_text":"Yu-Chieh Chung","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2010-08-15T09:12:09Z","title":"On Global Flipped SU(5) GUTs in F-theory"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1008.2506","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":"sha256:98fa6bc11ff66f605058460269e50828d6b20fea9583094812ccc87e43b33177","target":"record","created_at":"2026-05-18T04:25:28Z","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":"53db961772bdeefa0f28c0352ec9613a32e8d5625b2fdd7bd4e9761a6e123081","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2010-08-15T09:12:09Z","title_canon_sha256":"cd64aa908d7f8f2cb0bda8b9dc0fd9a744905a4169af8dfb627568b9ea85ae59"},"schema_version":"1.0","source":{"id":"1008.2506","kind":"arxiv","version":2}},"canonical_sha256":"1225cec2663eefeae7c99cfd1af4af0b1749817ade3cc7b101dd5fccbac38e11","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1225cec2663eefeae7c99cfd1af4af0b1749817ade3cc7b101dd5fccbac38e11","first_computed_at":"2026-05-18T04:25:28.147331Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:25:28.147331Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"acg3OGUGjGYxaO7D4fXR53NDsyrmx/wbZ5e5uz7G1QxT2VJ3OTWvppazKGTlBQXjM6JEiblNo80fg0hf3G72Dg==","signature_status":"signed_v1","signed_at":"2026-05-18T04:25:28.148028Z","signed_message":"canonical_sha256_bytes"},"source_id":"1008.2506","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:98fa6bc11ff66f605058460269e50828d6b20fea9583094812ccc87e43b33177","sha256:1e79ad4747a8d4eac8fd2eb2324cc2189a21fb378f773126281402c725e15756"],"state_sha256":"a89530cdf1a7dc7ce2409bc4ba0b8887cafa4830885a953f4911c908e091f4a9"}
