Chiral Fermion Delocalization in Deconstructed Higgsless Theories

TL;DR

This paper constructs a renormalizable Higgsless gauge theory with standard-model-like features, using a deconstructed extra dimension and unique fermion delocalization, achieving realistic weak interactions without a Higgs boson.

Contribution

It introduces a novel deconstructed Higgsless model with fermion delocalization across nodes, maintaining standard-model phenomenology at about 2 TeV.

Findings

Achieves standard-model-like gauge boson masses and weak interactions

Fermions are delocalized with left- and right-handed components on alternate nodes

Model remains renormalizable with all VEVs around 2 TeV

Abstract

{I construct a renormalizable $SU(2)^{89}\times U(1)$ gauge theory with standard-model-like phenomenology for the gauge bosons masses and the weak interactions of the light fermions (including the $b$) but in which all vacuum expectation values are about 2 TeV. This is a deconstructed version of a Higgsless model with a flat extra dimension. The fermions are delocalized on the theory space in an unusual way, with LH and RD fermions on alternate nodes.
