奇异谱数据的Yukawa纹理

Yukawa Textures From Singular Spectral Data

Mohsen Karkheiran

摘要:

利用奇异谱数据研究了有效杂种优势模型的Yukawa结构。这种方法的一个优点是可以将丛的上同调分解成更小的部分,并识别出包含零模的部分,这些零模可能具有非零的汤川耦合。另一个优点是在杂种模型和局部F-理论模型中的汤川纹理之间的明显关系,即在7-膜内的大量或局部场。我们这里只研究维尔斯特拉斯椭圆纤维卡-丘流形。文末给出了将这种方法推广到任意有理截面椭圆纤维Calabi-Yau方程的思想。

英文摘要:

The Yukawa textures of effective heterotic models are studied by using singular spectral data. One advantage of this approach is that it is possible to dissect the cohomologies of the bundles into smaller parts and identify the pieces that contain the zero modes, which can potentially have non-zero Yukawa couplings. Another advantage is the manifest relationship between the Yukawa textures in heterotic models and local F-theory models in terms of fields living in bulk or localized inside the 7-branes. We only work with Weierstrass elliptically fibered Calabi-Yau manifolds here. The idea for generalizing this approach to every elliptically fibered Calabi-Yau with rational sections is given at the end of this paper.
