非对易几何谱Action作为统一的框架:引论和唯象/宇宙学的结果

Noncommutative Geometry Spectral Action as a framework for unification: Introduction and phenomenological/cosmological consequences

Mairi Sakellariadou

摘要:

我将总结非对易几何谱作用量,这是一个在统一尺度上有效的优雅几何模型,它为粒子物理学中最成功的唯象模型标准模型提供了一个纯粹的引力解释。非对易几何指出,接近普朗克能量标度,时空具有精细结构,并提出它是四维连续紧致黎曼流形与微小离散有限非对易空间的乘积。光谱作用量原理是一种只依赖于狄拉克算子光谱的光谱作用量泛函,应用于几乎可交换的乘积几何,可以得到完整的标准模型,包括中微子混合,其中包含马约拉纳质量项和跷跷板机制,最小程度地与引力耦合。它还在统一尺度上做出了各种预测。我将回顾这种美丽的、纯粹的几何统一方法的一些现象学和宇宙学后果。

英文摘要:

I will summarize Noncommutative Geometry Spectral Action, an elegant geometrical model valid at unification scale, which offers a purely gravitational explanation of the Standard Model, the most successful phenomenological model of particle physics. Noncommutative geometry states that close to the Planck energy scale, space-time has a fine structure and proposes that it is given as the product of a four-dimensional continuum compact Riemaniann manifold by a tiny discrete finite noncommutative space. The spectral action principle, a universal action functional on spectral triples which depends only on the spectrum of the Dirac operator, applied to this almost commutative product geometry, leads to the full Standard Model, including neutrino mixing which has Majorana mass terms and a see-saw mechanism, minimally coupled to gravity. It also makes various predictions at unification scale. I will review some of the phenomenological and cosmological consequences of this beautiful and purely geometrical approach to unification.
