LHC Signatures of New Gauge Bosons in the Minimal Higgsless Model

TL;DR

This paper investigates how new gauge bosons predicted by the minimal Higgsless model could be detected at the LHC, focusing on their signatures in specific particle collision processes and analyzing background effects.

Contribution

It provides the first detailed analysis of LHC signatures for the W_1 and Z_1 bosons in the minimal Higgsless model, including background considerations and discovery potential.

Findings

W_1 bosons as light as 400 GeV can be detected at the LHC.

The study identifies complementary channels for W_1 discovery.

LHC has significant potential to discover W_1 across its allowed mass range.

Abstract

We study the LHC signatures of new gauge bosons in the gauge-invariant minimal Higgsless model. It predicts an extra pair of W_1 and Z_1 bosons which can be as light as ~400GeV and play a key role in the delay of unitarity violation. We analyze the W_1 signals in pp --> W_0Z_0Z_0 --> jj4\ell and pp --> jj W_0Z_0 --> jj3\ell\nu processes at the LHC, including the complete electroweak and QCD backgrounds. We reveal the complementarity between these two channels for discovering the W_1 boson, and demonstrate the LHC discovery potential over the full range of allowed W_1 mass.
