利用复曲面几何构造了一类全局F-理论GUT模型。基流形是Fano三重流形的爆破,而Calabi-Yau四重流形是两个超曲面的完全交。我们识别可能的GUT因子,并使用谱覆盖构造在其上构建SO(10)模型。为了获得更多的唯象自由度,我们使用分裂光谱覆盖在10条曲线上产生手征物质。我们用交换流将SO(10)破缺为SU(5)×U(1),这是一个翻转的SU(5)模型。有了SU(5)× U(1)模型中的GUT希格斯粒子,就有可能进一步打破标准模型的规范对称性。我们详细介绍了几个现象学上有吸引力的例子。
Making use of toric geometry we construct a class of global F-theory GUT models. The base manifolds are blowups of Fano threefolds and the Calabi-Yau fourfold is a complete intersection of two hypersurfaces. We identify possible GUT divisors and construct SO(10) models on them using the spectral cover construction. We use a split spectral cover to generate chiral matter on the 10 curves in order to get more degrees of freedom in phenomenology. We use abelian flux to break SO(10) to SU(5) ×U(1) which is interpreted as a flipped SU(5) model. With the GUT Higgses in the SU(5) × U(1) model it is possible to further break the gauge symmetry to the Standard Model. We present several phenomenologically attractive examples in detail.
