20.500.12556/DKUM-86169 String Universality and Non-Simply-Connected Gauge Groups in 8D We present a consistency condition for 8D N 1 supergravity theories with nontrivial global structure G=Z for the non-Abelian gauge group, based on an anomaly involving the Z 1-form center symmetry. The interplay with other swampland criteria identifies the majority of 8D theories with gauge group G=Z, which have no string theory realization, as inconsistent quantum theories when coupled to gravity. While this condition is equivalent to geometric properties of elliptic K3 surfaces in F-theory compactifications, it constrains the unexplored landscape of gauge groups in other 8D string models. supergravity theories string theory 8D string models supergravitacija teorija strun 8D model strun true false true American Physical Society Angleški jezik Slovenski jezik Znanstveno delo 2023-10-16 14:09:00 2023-10-16 14:59:01 2025-01-16 14:16:12 0000-00-00 00:00:00 2020 0 0 Str. 1-6 št. 21, št. članka 211602 Letn. 125 nov. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-09-03 2020-11-04 2020-11-20 530.145 56557571 10.1103/PhysRevLett.125.211602 1079-7114 String_Universality_and_Non-Simply-Connected_Gauge_Groups_Cvetic_2020.pdf String_Universality_and_Non-Simply-Connected_Gauge_Groups_Cvetic_2020.pdf 1 3650FA72D5507773B5335F3A792B20DC fab20f601fc0ef5503fad6099d7aee120ef84c120e72dd6ec087a5621fe485e6 ada41fe6-6c23-11ee-aee9-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173599 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.211602 0 b57680bd-6c23-11ee-aee9-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173600 Univerza v Mariboru 0 0 0
