Redesigning Electroweak Theory: Does the Higgs Particle Exist?

TL;DR

This paper proposes a Higgsless electroweak model where particle masses arise from quantum loop graphs, maintaining gauge invariance and unitarity, and accurately predicts the W boson mass without a Higgs particle.

Contribution

It introduces a finite, gauge-invariant electroweak theory without a Higgs particle, using a regularization scheme that preserves unitarity and Poincare invariance.

Findings

Predicts W boson mass with 0.5% accuracy

Maintains unitarity at high energies without a Higgs

Provides a finite, gauge-invariant quantum field theory

Abstract

An electroweak model in which the masses of the W and Z bosons and the fermions are generated by quantum loop graphs through a symmetry breaking is investigated. The model is based on a regularized quantum field theory in which the quantum loop graphs are finite to all orders of perturbation theory and the massless theory is gauge invariant, Poincare invariant, and unitary. The breaking of the electroweak symmetry SU(2) X U(1) is achieved without a Higgs particle. A fundamental energy scale of ~542 GeV (not to be confused with a naive cutoff) enters the theory through the regularization of the Feynman loop diagrams. The theory yields a prediction for the W mass that is accurate to about 0.5% without radiative corrections. The scattering amplitudes for WW -> WW and e+e- -> WW processes do not violate unitarity at high energies due to the suppression of the amplitudes by the running of the coupling constants at vertices.
