CDF W mass anomaly revisited

TL;DR

This paper investigates the observed decline in W boson mass measurements at different collider energies, proposing a model that could explain this trend as a potential signal of metric field effects at high energies.

Contribution

It introduces a novel model to explain the energy-dependent decline in W boson mass measurements observed across multiple collider experiments.

Findings

The model accounts for the decreasing trend in W mass with increasing collider energy.

It suggests a possible link between the trend and metric field effects at high energies.

The paper explores properties and implications of the proposed model.

Abstract

The CDF, ATLAS and LHCb have released the measurements on the W boson mass $m_W$ at $\sqrt{S}=1.96, 7, 13 TeV$, respectively. The measured values show the declining tendency, namely $m_W$ decreases with the increment of the collider energy. If the declining tendency is confirmed, it might be the signal of metric field at high energy colliders. In this paper, we propose a model to account for such tendency and explore the properties of the model.
