Z(8)环面轨道褶皱上的类MSSM模型

MSSM-like models on Z(8) toroidal orbifolds

Stefan Groot Nibbelink, Orestis Loukas

摘要:

我们扩展了有前途的杂种优势字符串搜索MSSM类模型的Z_8 orbifolds。存在五个不等价的Z_8环面轨道折叠,它们由作用在五个不同环面格上的两种类型的扭曲区分,其中一个不能表示为李代数根格。与以往的调查,我们研究的后果不同的基础orbifold环面晶格。因此,我们不是集中在一个特定的几何,同时对这五个Z_8轨道进行系统的模型搜索,把所有可能的不等价SU(5)和SO(10)规范位移作为我们的出发点。我们提出了累积的表格和图比较手性SM和矢量样异国情调的光谱在这些几何形状。

英文摘要:

We extend the promising heterotic string searches for MSSM-like models to Z_8 orbifolds. There exist five inequivalent Z_8 toroidal orbifolds distinguished by two types of twists that act on five different torus lattices; one of which cannot be represented as a Lie-algebra root lattice. Contrary to previous investigations, we study the consequences of the different underlying orbifold torus lattices. Therefore, rather than focussing on one particular geometry, we perform systematic model searches on these five Z_8 orbifolds simultaneously, taking all possible inequivalent SU(5) and SO(10) gauge shifts as our starting point. We present cumulative Tables and Figures comparing the chiral SM and vector-like exotic spectra on these geometries.
