Phenomenology of Higgsless Models at the LHC and the ILC

TL;DR

This paper explores how Higgsless models can be tested at future colliders like the LHC and ILC, focusing on vector boson scattering and resonance detection to verify the absence of a Higgs boson.

Contribution

It provides a detailed analysis of Higgsless model signatures at colliders, emphasizing model-independent tests and discovery potential at the LHC and ILC.

Findings

LHC can probe all preferred Higgsless parameter space with 100 fb^{-1}

Vector boson scattering tests can verify Higgsless mechanism

Higgsless models have promising discovery prospects at the ILC

Abstract

We investigate the signatures of the recently proposed Higgsless models at future colliders. We focus on tests of the mechanism of partial unitarity restoration in the longitudinal vector boson scattering, which do not depend on any Higgsless model-building details. We study the LHC discovery reach for charged massive vector boson resonances and show that all of the preferred parameter space will be probed with $100 {\rm fb}^{-1}$ of LHC data. We also discuss the prospects for experimental verification of the Higgsless nature of the model at the LHC. In addition, in this talk we present new results relevant for the discovery potential of Higgsless models at the International Linear Collider (ILC).
