20.500.12556/DKUM-86154 Higher-form symmetries and their anomalies in M-/F-theory duality We explore higher-form symmetries of M- and F-theory compactified on elliptic fibrations, determined by the topology of their asymptotic boundaries. The underlying geometric structures are shown to be equivalent to known characterizations of the gauge group topology in F-theory via Mordell-Weil torsion and string junctions. We further study dimensional reductions of the 11d Chern-Simons term in the presence of torsional boundary G4-fluxes, which encode background gauge fields of center one-form symmetries in the lower-dimensional effective gauge theory. We find contributions that can be interpreted as ’t Hooft anomalies involving the one-form symmetry which originate from a fractionalization of the instanton number of non-Abelian gauge theories in F-/M-theory compactifications to 8d=7d and 6d=5d. astrophysics anomalies compactification M-theory string dualities discrete symmetries symmetries astrofizika anomalije zgoščevanje M-teorija dvojnost strun diskretne simetrije simetrije true false true American Physical Society Angleški jezik Slovenski jezik Znanstveno delo 2023-10-13 14:45:15 2023-10-13 14:54:55 2024-08-09 13:22:54 0000-00-00 00:00:00 2021 0 0 Str. 1-28 Št. 12, št. članka 126019 Letn. 104 22. dec. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-08-04 2021-11-10 2021-12-22 52 97889795 10.1103/PhysRevD.104.126019 2470-0029 Higher-form_symmetries_Cvetic_2021.pdf Higher-form_symmetries_Cvetic_2021.pdf 1 AB0BAC9F9A8715AA8E827EE6AA306EAF e0c71ada04a6828510cb29a136e39836d7ac826f06de3990300f73d16b8d72c1 7e70a518-69c7-11ee-b6cb-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173559 https://journals.aps.org/prd/abstract/10.1103/PhysRevD.104.126019 0 60a346d6-69c6-11ee-b6cb-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173558 Univerza v Mariboru 0 0 0
