具有稳定模量的超对称SU(5)GUT

Supersymmetric SU(5) GUT with Stabilized Moduli

Ignatios Antoniadis, Alok Kumar, Binata Panda

摘要:

我们构造了一个磁化D ~ 9-膜的第一类弦论的超对称大统一模型的极小例子。所有的几何模量稳定的背景内部磁通量是“斜”型(相互非交换)。规范对称性为SU(5),规范非单重手征谱仅包含三族在$10+{\bar 5}$表象中变换的夸克和轻子。

英文摘要:

We construct a minimal example of a supersymmetric grand unified model in a toroidal compactification of type I string theory with magnetized D9-branes. All geometric moduli are stabilized in terms of the background internal magnetic fluxes which are of "oblique" type (mutually non-commuting). The gauge symmetry is just SU(5) and the gauge non-singlet chiral spectrum contains only three families of quarks and leptons transforming in the $10+{\bar 5}$ representations.
