Composite Weak Bosons, Leptons and Quarks

TL;DR

This paper proposes that weak bosons, leptons, and quarks are composite particles bound by a new confining force, predicting new particles and resonances at TeV energy scales.

Contribution

It introduces a composite model for weak bosons, leptons, and quarks, and predicts a new neutral weak boson X and high-energy resonances.

Findings

Existence of a neutral isoscalar weak boson X below 1 TeV.

Predicted decay modes of X into quark/lepton pairs and weak bosons.

Resonances of leptons and quarks at energies above 1 TeV.

Abstract

The weak bosons consist of two fermions, bound by a new confining gauge force. The mass scale of this new interaction is determined. At energies below 0.5 TeV the standard electroweak theory is valid. A neutral isoscalar weak boson X must exist - its mass is less than 1 TeV. It will decay mainly into quark and lepton pairs and into two or three weak bosons. Above the mass of 1 TeV one finds excitations of the weak bosons, which mainly decay into pairs of weak bosons. Leptons and quarks consist of a fermion and a scalar. Pairs of leptons and pairs of quarks form resonances at very high energy.
