A toy model for the W/Z mass ratio

TL;DR

This paper examines whether recent theoretical models can explain a significant anomaly in the W/Z mass ratio, which, if confirmed, would challenge the Standard Model of particle physics.

Contribution

It evaluates the potential of recently proposed models to resolve the W/Z mass ratio anomaly, highlighting their theoretical viability.

Findings

Models can, in principle, address the anomaly

Further experimental confirmation is needed

Theoretical extensions are plausible

Abstract

The recently reported $7\sigma$ anomaly in measurements of the W/Z mass ratio, if confirmed, will demand an extension of some kind to the standard model of particle physics. In this paper I consider whether some recently proposed models are capable, in principle, of resolving this anomaly, subject to experimental confirmation.
