Gauge Boson and Fermion Masses Without a Higgs Field

TL;DR

This paper proposes a novel mechanism within a specific chiral gauge theory that allows for the generation of fermion and gauge boson masses without relying on a Higgs field, potentially impacting electroweak theory.

Contribution

It introduces a perturbative quantisation and renormalisation approach for anomaly-free chiral gauge theories that naturally produce particle masses without a Higgs mechanism.

Findings

Fermion and gauge boson masses can be generated without a Higgs field.

The approach exploits freedoms in the unperturbed Lagrangian and renormalisation.

The mechanism is anomaly-free and perturbatively consistent.

Abstract

A simple, anomaly-free chiral gauge theory can be perturbatively quantised and renormalised in such a way as to generate fermion and gauge boson masses. This development exploits certain freedoms inherent in choosing the unperturbed Lagrangian and in the renormalisation procedure. Apart from its intrinsic interest, such a mechanism might be employed in electroweak gauge theory to generate fermion and gauge boson masses without a Higgs sector.
