A Renormalization Group Analysis of the NCG constraints $m_{top} = 2\,m_W}$, $m_{Higgs} = 3.14 \, m_W$

TL;DR

This paper investigates how the non-commutative geometry constraints on top and Higgs masses evolve with energy scale using renormalization group analysis, showing weak dependence on the chosen scale.

Contribution

It provides a renormalization group analysis of NCG-derived mass relations, highlighting their weak scale dependence and interpretation as tree-level constraints.

Findings

Mass relations are stable under RG flow.

Weak dependence of physical masses on the energy scale.

Constraints can be applied at a specific energy scale.

Abstract

We study the evolution under the renormalization group of the restrictions on the parameters of the standard model coming from Non-Commutative Geometry, namely $m_{top} = 2\,m_W$ and $m_{Higgs} = 3.14 \, m_W$. We adopt the point of view that these relations are to be interpreted as {\it tree level} constraints and, as such, can be implemented in a mass independent renormalization scheme only at a given energy scale $\mu_0$. We show that the physical predictions on the top and Higgs masses depend weakly on $\mu_0$.
