20.500.12556/DKUM-86155 Gauge group topology of 8D Chaudhuri-Hockney-Lykken vacua Compactifications of the Chaudhuri-Hockney-Lykken (CHL) string to eight dimensions can be characterized by embeddings of root lattices into the rank 12 momentum lattice ΛM, the so-called Mikhailov lattice. Based on these data, we devise a method to determine the global gauge group structure including all Uð1Þ factors. The key observation is that, while the physical states correspond to vectors in the momentum lattice, the gauge group topology is encoded in its dual. Interpreting a nontrivial π1ðGÞ ≡ Z for the non-Abelian gauge group G as having gauged a Z 1-form symmetry, we also prove that all CHL gauge groups are free of a certain anomaly [1] that would obstruct this gauging. We verify this by explicitly computing Z for all 8D CHL vacua with rankðGÞ ¼ 10. Since our method applies also to T2 compactifications of heterotic strings, we further establish a map that determines any CHL gauge group topology from that of a “parent” heterotic model. astrophysics compactification string dualities string and branes discrete symmetries symmetries gauge symmetries astrofizika zgoščevanje dvojnost strun strune in brane diskretne simetrije simetrije merjenje simetrij true false true American Physical Society Angleški jezik Slovenski jezik Znanstveno delo 2023-10-13 15:03:22 2023-10-13 15:15:04 2024-08-09 13:17:09 0000-00-00 00:00:00 2021 0 0 Str. 1-18 Št. 8, št. članka 086018 Letn. 104 12. okt. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-08-04 2021-09-03 2021-10-12 52 97890307 2470-0029 Gauge_group_topology_Cvetic_2021.pdf Gauge_group_topology_Cvetic_2021.pdf 1 1C1A49EC60704A06AE19613064AA1ADD 2dcb12f4bf4ef5bb311c629e2c26330b8c7ede54ab9c252fda65e13d44f842ca 208a0f4f-69ca-11ee-b6cb-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173561 https://journals.aps.org/prd/abstract/10.1103/PhysRevD.104.086018 0 e8d2d00b-69c8-11ee-b6cb-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=173560 Univerza v Mariboru 0 0 0
