20.500.12556/DKUM-86197 Constraints on standard model constructions in F-theory We argue that the following three statements cannot all be true: (i) our vacuum is a type IIB/F-theory vacuum at moderate to large h(1,1); (ii) the alpha' expansion is controlled via the supergravity approximation, a la the Kachru-Kallosh-Linde-Trivedi and Large Volume scenarios; and (iii) there are no additional gauged sectors from 7-branes. Since nearly all known globally consistent F-theory models with the exact chiral spectrum of the Standard Model and gauge coupling unification occur at moderate h(1,1), this finding calls for new moduli stabilization scenarios or/and a rich 7-brane dark sector. brane worlds compactification string theory zgoščevanje teorija strun true false true American Physical Society Angleški jezik Slovenski jezik Znanstveno delo 2023-10-23 10:10:53 2023-10-23 10:30:54 2025-01-16 15:33:59 0000-00-00 00:00:00 2020 0 0 Str. 1-10 št. 2, št. članka 026012 Letn. 102 10. jul. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-04-30 2020-07-01 2020-07-10 530.122.3 56588547 10.1103/PhysRevD.102.026012 2470-0029 Constraints_on_standard_model_constructions_Cvetic_2020.pdf Constraints_on_standard_model_constructions_Cvetic_2020.pdf 1 7D2E9A5AA660106DB302977461AAE092 6826c2a57ed904400fb5829512f68a34e0130ed1817df83285ce8bd7ca83394d 3d272953-717e-11ee-9019-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173687 https://journals.aps.org/prd/abstract/10.1103/PhysRevD.102.026012 0 476a9133-717e-11ee-9019-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173688 Univerza v Mariboru 0 0 0
