These models are the minimal setting in which the whole flavour structure for the MSSM charged fermions is encoded in a small region of the entire compactification space. In this setup the $E_7$ symmetry is broken down to SU(5) by means of a 7-brane T-brane background, and further to the MSSM gauge group by means of a hypercharge flux that also implements doublet-triplet splitting. At tree-level only one family of quarks and charged leptons is massive, while the other two obtain hierarchically s","authors_text":"Federico Carta, Fernando Marchesano, Gianluca Zoccarato","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2015-12-15T16:37:30Z","title":"Fitting fermion masses and mixings in F-theory GUTs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1512.04846","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":"sha256:234068a415f4b2fd4909f0207b97110c0f63bca63cf30de0fad2a5778043f54b","target":"record","created_at":"2026-05-18T01:16:44Z","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":"ac160829e29b343ace2fda385e94203e62a4b5976ab0feff4eccddea74dbe700","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2015-12-15T16:37:30Z","title_canon_sha256":"5284796bedddafba7817d4cfa990bf984a2e427fb7f58f76beb6917ddf5a1f45"},"schema_version":"1.0","source":{"id":"1512.04846","kind":"arxiv","version":2}},"canonical_sha256":"7ce4ca432f2face8040b5009d5eb15b9621cd3b57d96531dcd2e76bee3c85b5c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7ce4ca432f2face8040b5009d5eb15b9621cd3b57d96531dcd2e76bee3c85b5c","first_computed_at":"2026-05-18T01:16:44.618844Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:16:44.618844Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XpCVuTQKINiLByJUN/1nNDbwX36AZFuRPu4LAPCWggDJFivenibwKwjH/rljmJaEyTFXKInJitM4gbhh5Ke5DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:16:44.619479Z","signed_message":"canonical_sha256_bytes"},"source_id":"1512.04846","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:234068a415f4b2fd4909f0207b97110c0f63bca63cf30de0fad2a5778043f54b","sha256:0edc8e5f3e79d2ea421aa4a01455f234dbfeca39e7b9a4a862f8e8dafa2c7443"],"state_sha256":"dacdb59bce7a68d87b7461152fcb9d42daf0907541cf72f64f208102292ae0dc"}
