非对易几何中的新标量场

New Scalar Fields in Noncommutative Geometry

Christoph A. Stephan

摘要:

在这篇文章中,我们在Connes的非对易几何[1]的框架内提出了标准模型的一个推广。本文提出的模型是基于一个最小谱三元组[7],它包含标准模型粒子、新的类矢量费米子和一个新的U(1)规范子群。此外,一个新的复杂的标量场出现,耦合到右手中微子,新的费米子和标准的希格斯粒子。作用量的玻色子部分由谱作用量[1]给出,它也决定了截止能量为ca时规范耦合、四次标量耦合和Yukawa耦合之间的关系。10^(17)GeV。我们研究这些关系的重正化群流。低能量行为允许约束希格斯质量,新标量的质量和这两个标量场之间的混合。

英文摘要:

In this publication we present an extension of the Standard Model within the framework of Connes' noncommutative geometry [1]. The model presented here is based on a minimal spectral triple [7] which contains the Standard Model particles, new vectorlike fermions and a new U(1) gauge subgroup. Additionally a new complex scalar field appears that couples to the right-handed neutrino, the new fermions and the standard Higgs particle. The bosonic part of the action is given by the spectral action [1] which also determines relations among the gauge couplings, the quartic scalar couplings and the Yukawa couplings at a cut-off energy of ca. 10^(17) GeV. We investigate the renormalisation group flow of these relations. The low energy behaviour allows to constrain the Higgs mass, the mass of the new scalar and the mixing between these two scalar fields.
