Classification of symmetric toroidal orbifolds

Maximilian Fischer, Michael Ratz, Jesus Torrado, Patrick K. S. Vaudrevange

摘要:

我们提供了一个完整的分类六维对称环形orbifolds产生N>=1的超对称性在4D的杂化弦。我们的策略是基于六维晶体空间群的分类。我们共发现520个不等的环面轨道折叠,其中162个具有Abel点群,如Z_3,Z_4,Z_6-I等,358个具有非Abel点群,如S_3,D_4,A_4等。即指定Hodge数并评论规范对称性破缺的可能机制(局域或非局域)。

英文摘要:

We provide a complete classification of six-dimensional symmetric toroidal orbifolds which yield N>=1 supersymmetry in 4D for the heterotic string. Our strategy is based on a classification of crystallographic space groups in six dimensions. We find in total 520 inequivalent toroidal orbifolds, 162 of them with Abelian point groups such as Z_3, Z_4, Z_6-I etc. and 358 with non-Abelian point groups such as S_3, D_4, A_4 etc. We also briefly explore the properties of some orbifolds with Abelian point groups and N=1, i.e. specify the Hodge numbers and comment on the possible mechanisms (local or non-local) of gauge symmetry breaking.
