Deciphering the spin of new resonances in Higgsless models

TL;DR

This paper evaluates the LHC's ability to determine the spin of new vector boson resonances predicted by Higgsless models through weak boson fusion, showing it can distinguish spin with sufficient luminosity.

Contribution

It demonstrates the feasibility of using weak boson fusion at the LHC to identify the spin of new resonances in Higgsless models, a novel approach in this context.

Findings

LHC can determine the spin of new resonances with 150-560 fb^-1 luminosity.

The method relies on the coupling between resonances and weak gauge bosons.

Spin determination is feasible across various resonance masses.

Abstract

We study the potential of the CERN Large Hadron Collider (LHC) to probe the spin of new massive vector boson resonances predicted by Higgsless models. We consider its production via weak boson fusion which relies only on the coupling between the new resonances and the weak gauge bosons. We show that the LHC will be able to unravel the spin of the particles associated with the partial restoration of unitarity in vector boson scattering for integrated luminosities of 150-560 fb^-1, depending on the new state mass and on the method used in the analyses.
