Composite Weak Bosons: a Lattice Analysis

TL;DR

This paper investigates a confining Yang-Mills theory through lattice methods, proposing it as a potential model for composite weak bosons, with analytical and numerical evidence supporting its viability.

Contribution

It provides the first lattice analysis of a Goldstone-boson-free confining Yang-Mills theory as a candidate for composite weak bosons, combining strong coupling expansion and Monte Carlo simulations.

Findings

The theory is confining without Goldstone bosons.

Lattice simulations support the composite weak boson hypothesis.

Analytical and numerical methods agree on key properties.

Abstract

We present a lattice analysis of a confining Yang-Mills theory without Goldstone boson. We have analytically investigated the model by a strong coupling expansion and by an intensive lattice Monte Carlo simulation using standard lattice QCD methods. We show that this theory is an interesting candidate for describing weak bosons as composite particles.
