As a concrete proposal for such a construction, we consider a single probe D3-brane on a partial resolution of a del Pezzo 8 singularity. The resulting world-volume theory reproduces the field content and interactions of the MSSM, however with a somewhat extended Higgs sector. An attractive feature of our approach is that the gauge and Yukawa couplings are dual to non-dynamical closed string modes, and are therefore tunable parameters.","authors_text":"Herman Verlinde, Martijn Wijnholt","cross_cats":[],"headline":"","license":"","primary_cat":"hep-th","submitted_at":"2005-08-12T19:27:47Z","title":"Building the Standard Model on a D3-brane"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"hep-th/0508089","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":"sha256:449bcfe487ce32c6031080e4518f32ee96de10d6895c5c5463173105857f6dad","target":"record","created_at":"2026-05-18T04:38:26Z","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":"45813440fab88a360e809214a40671a14bfc770ff86f23461cba3423e9fd63d6","cross_cats_sorted":[],"license":"","primary_cat":"hep-th","submitted_at":"2005-08-12T19:27:47Z","title_canon_sha256":"0d81af9caeb7da8ac30024ddaf35fab5b3a9d5a609fa1b5fec59ee151592d5ae"},"schema_version":"1.0","source":{"id":"hep-th/0508089","kind":"arxiv","version":2}},"canonical_sha256":"4c052eebf9e28264066fa20594492ce7b2f55f89ffbbb154ee921c1a51bde486","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4c052eebf9e28264066fa20594492ce7b2f55f89ffbbb154ee921c1a51bde486","first_computed_at":"2026-05-18T04:38:26.950734Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:38:26.950734Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xnyk6Ifkn4PyUeesJzGCL2ZTgwgWMqjP7UjLxo0mpYhWKsExpvpCldFyDUHN95sIXKTUVucgz5nYKC+tefJHDA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:38:26.951378Z","signed_message":"canonical_sha256_bytes"},"source_id":"hep-th/0508089","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:449bcfe487ce32c6031080e4518f32ee96de10d6895c5c5463173105857f6dad","sha256:f5e0d7c955b5d9fac9c2f470dd514b622aaa23ede3d9a0aaa90ec76c70937208"],"state_sha256":"27b6b4d817cf2cc46e931002529557058b457ad974eb747eba025abcf42140d2"}
