20.500.12556/DKUM-69869 Type II string theory on Calabi-Yau manifolds with torsion and non-Abelian discrete gauge symmetries We provide the first explicit example of Type IIB string theory compactification on a globally defined Calabi-Yau threefold with torsion which results in a four-dimensional effective theory with a non-Abelian discrete gauge symmetry. Our example is based on a particular Calabi-Yau manifold, the quotient of a product of three elliptic curves by a fixed point free action of Z(2) x Z(2). Its cohomology contains torsion classes in various degrees. The main technical novelty is in determining the multiplicative structure of the (torsion part of) the cohomology ring, and in particular showing that the cup product of second cohomology torsion elements goes non-trivially to the fourth cohomology. This specifies a non-Abelian, Heisenberg-type discrete symmetry group of the four-dimensional theory. string field theory conformal field models string theory discrete symmetries teorija superstrun kvantna logika fizika elementarnih delcev true false true Angleški jezik Slovenski jezik Znanstveno delo 2018-03-08 09:27:56 2018-03-08 09:29:07 2022-08-01 18:15:54 2019-07-11 17:47:16 2017 0 0 str. 1-21 št. 7 2017 jul. 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1029-8479 530.122.3 1314148 94082049 10.1007/JHEP07(2017)129 1029-8479 URN:SI:UM:DK:BNRQYKEU Journal_of_High_Energy_Physics_2017_Braun_et_al._Type_II_string_theory_on_Calabi-Yau_manifolds_with_torsion_and_non-Abelian_discrete_gau.pdf Journal_of_High_Energy_Physics_2017_Braun_et_al._Type_II_string_theory_on_Calabi-Yau_manifolds_with_torsion_and_non-Abelian_discrete_gau.pdf 1 DA47337A01D9F42107DD873820A3699F 680ef555cd5d133f273d17767f140d2f5284458b2bd0ddc677153efd3e1d3c1e b54526c6-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/b3e403b8-1837-4470-8ef1-bd83306ddf2d https://dk.um.si/Dokument.php?lang=slv&id=122483 http://link.springer.com/10.1007/JHEP07(2017)129 1 https://dk.um.si/Dokument.php?lang=slv&id=122482 Univerza v Mariboru 0 0 0
