标准模型II之外的几乎可换几何:新的颜色

Almost-Commutative Geometries Beyond the Standard Model II: New Colours

Christoph A. Stephan

摘要:

我们将介绍粒子物理学的标准模型在几乎对易表述中的一个扩展。这种扩展是由[13]中所采用的几乎对易几何的最小方法指导的,尽管这里提出的模型本身并不是最小的。相应的几乎对易几何导致一个杨-米尔斯-希格斯模型,它由标准模型和两个新的费米子相反的电磁荷,可能具有一个新的颜色,如规范群。作为一种新的现象,大统一不再是谱作用量所必需的。

英文摘要:

We will present an extension of the standard model of particle physics in its almost-commutative formulation. This extension is guided by the minimal approach to almost-commutative geometries employed in [13], although the model presented here is not minimal itself. The corresponding almost-commutative geometry leads to a Yang-Mills-Higgs model which consists of the standard model and two new fermions of opposite electro-magnetic charge which may possess a new colour like gauge group. As a new phenomenon, grand unification is no longer required by the spectral action.
