Lalla Btissam Drissi, Leila Medari, El Hassan Saidi

摘要:

在Beasley-Heckman-Vafa理论框架下研究了一类四维$\mathcal{N}=1$超对称GUT型模型.我们首先回顾了MSSM和超对称大统一理论的一般结果,并描述了在F-理论框架下的四维规范规范理论的有用工具。然后我们基于复四面体表面$\mathcal{T}$及其爆破体$\mathcal{T}_{n}$,研究了定域椭圆CY 4上F-理论中包裹4-圈的7-膜中的有效超对称规范理论。复杂二维几何$\mathcal{T}$和$\mathcal{T}_{n}$是\emph{non planar}投影曲面,它们扩展了投影平面$\mathbb{P}^{2}$和del Pezzos。利用复曲面几何的幂对局部CY 4基的复曲面数据进行编码,建立了一类基于$\mathcal{T}$和$\mathcal{T}_{n}$的\emph{4D} $\mathcal{N}=1$非极小GUT型模型。给出了SU $(5) $ GUT型模型的显式构造。

英文摘要:

We study a class of 4D $\mathcal{N}=1$ supersymmetric GUT- type models in the framework of the Beasley-Heckman-Vafa theory. We first review general results on MSSM and supersymmetric GUT; and we describe useful tools on 4D quiver gauge theories in F- theory set up. Then we study the effective supersymmetric gauge theory in the 7-brane wrapping 4-cycles in F-theory on local elliptic CY4s based on a complex tetrahedral surface $\mathcal{T}$ and its blown ups $\mathcal{T}_{n}$. The complex 2d geometries $\mathcal{T}$ and $\mathcal{T}_{n}$ are \emph{non planar} projective surfaces that extend the projective plane $\mathbb{P}^{2}$ and the del Pezzos. Using the power of toric geometry encoding the toric data of the base of the local CY4, we build a class of \emph{4D} $\mathcal{N}=1$ non minimal GUT- type models based on $\mathcal{T}$ and $\mathcal{T}_{n}$. An explicit construction is given for the SU$(5) $ GUT-type model.
