我们用蒙特卡罗方法研究了支撑四重椭圆Calabi-Yau四重基的环面三重基集合,并研究了几何不可Higgsable规范群、物质和箭图结构的分布。我们估计所研究的连通集合中不同的三重碱基的数量为∼1048。H1,1∼82附近的碱基峰分布。“热化”后遇到的所有碱基都有某种几何非希格斯结构。我们发现,非Higgsable规范群因子的数量在三重基数的h1,1中近似线性增长。典型的碱基有∼6孤立的规范因子,以及几个更大的带有共同带电物质的规范因子的连接星团。约76%的碱基含有形式为SU(3)×SU(2)的连通双因素规范群乘积,可作为标准模型规范群的非阿贝尔部分。SU(3)×SU(2)是第三个最常见的连通双因素乘积群,仅次于出现频率更高的SU(2)×SU(2)和G2×SU(2)。
A bstractWe use Monte Carlo methods to explore the set of toric threefold bases that support elliptic Calabi-Yau fourfolds for F-theory compactifications to four dimensions, and study the distribution of geometrically non-Higgsable gauge groups, matter, and quiver structure. We estimate the number of distinct threefold bases in the connected set studied to be ∼ 1048. The distribution of bases peaks around h1,1 ∼ 82. All bases encountered after “thermalization” have some geometric non-Higgsable structure. We find that the number of non-Higgsable gauge group factors grows roughly linearly in h1,1 of the threefold base. Typical bases have ∼ 6 isolated gauge factors as well as several larger connected clusters of gauge factors with jointly charged matter. Approximately 76% of the bases sampled contain connected two-factor gauge group products of the form SU(3) × SU(2), which may act as the non-Abelian part of the standard model gauge group. SU(3) × SU(2) is the third most common connected two-factor product group, following SU(2) × SU(2) and G2 × SU(2), which arise more frequently.
