Electroweak Symmetry Breaking without a Higgs Boson at the LHC

TL;DR

This paper explores alternative mechanisms for electroweak symmetry breaking at the LHC, focusing on vector boson scattering and technirho searches without a Higgs boson, proposing detectable signals within current experimental capabilities.

Contribution

It introduces two studies on strong symmetry breaking scenarios at the LHC, employing the Electroweak Chiral Lagrangian and Technicolour models to identify potential signals.

Findings

Vector boson scattering signals detectable with 30 fb^{-1}

Technirho discovery possible with 4 fb^{-1}

Signals could be observed at current LHC luminosities

Abstract

We present two studies into strong symmetry breaking scenarios at the LHC. The first case is a study into vector boson scattering at ATLAS. This uses the framework of the Electroweak Chiral Lagrangian with Pade unitarisation to generate possible signal scenarios. Signals could be observed with an integrated luminosity of 30 fb^{-1}. Secondly a search for the technirho, rho_{TC}, at CMS is presented, within the Technicolour ``Straw Man'' model. 5 sigma discovery is possible starting from 4 fb^{-1}.
