To illustrate our approach, we explicitly construct a local $\mathrm{dP}_{5}$ model via a combination of Higgsing and orientifolding. This procedure reduces the original $\mathrm{dP}_{5}$ quiver gauge theory to the Left-Right symmetric model with three families of quarks and leptons as well as a Higgs sector to further break the symmetries to the Standard Model gauge group. We embed this local model in a globally consistent Calabi-Yau flux compactification with tadpole and Freed-Witten anomaly cancellations. The model features closed string moduli stabilisation with a de Sitter minimum from T-branes, supersymmetry broken by the K\"ahler moduli, and the MSSM as the low energy spectrum. We further discuss phenomenological and cosmological implications of this construction. dc.language en dc.publisher Springer Science and Business Media LLC dc.subject Regular Article - Theoretical Physics dc.subject D-branes dc.subject Flux compactifications dc.subject Superstring Vacua dc.title The Standard Model quiver in de Sitter string compactifications dc.type Article dc.date.updated 2021-11-24T16:22:06Z prism.issueIdentifier 8 prism.publicationName Journal of High Energy Physics prism.volume 2021 dc.identifier.doi 10.17863/CAM.78478 dcterms.dateAccepted 2021-08-04 rioxxterms.versionofrecord 10.1007/JHEP08(2021)109 rioxxterms.version VoR rioxxterms.licenseref.uri http://creativecommons.org/licenses/by/4.0/ dc.contributor.orcid Schachner, Andreas [0000-0002-7287-1476] dc.identifier.eissn 1029-8479 dc.publisher.url http://dx.doi.org/10.1007/JHEP08(2021)109 cam.issuedOnline 2021-08-23 dc.identifier.arxiv 2106.11964
