TL;DR

This paper proposes a novel composite Higgs boson model made from gauge bosons, deriving its mass and interactions from gauge theory principles, potentially extending beyond the standard model.

Contribution

It introduces a gauge boson-based composite Higgs model, replacing scalar parameters with gauge self-interactions, and generalizes the Higgs mechanism to vector fields.

Findings

The model derives Higgs properties from gauge interactions without adjustable parameters.

Applicable to non-abelian gauge theories like grand unified models and supersymmetry.

Abstract

It is proposed to replace the Higgs boson of the standard model by a Lorentz- and gauge-invariant combination of SU(2) gauge bosons. A pair of Higgs bosons is identified with pairs of gauge bosons by setting their mass Lagrangians equal to each other. That immediately determines the mass of the composite Higgs boson. It becomes simply half of the vacuum expectation value of the standard Higgs boson, which matches the observed mass with tree-level accuracy (2%). The two parameters of the standard Higgs potential are replaced by five one-loop self-interactions of the SU(2) gauge bosons, derived from the fundamental gauge couplings. The Brout-Englert-Higgs mechanism of spontaneous symmetry breaking is generalized from scalars to vectors. Their transverse components acquire finite vacuum expectation values which generate masses for both gauge bosons and the Higgs boson. This concept leads beyond the standard model by enabling calculations of the Higgs mass and its potential without adjustable parameters. It can be applied to non-abelian gauge theories in general, such as grand unified models and supersymmetry.
