How well can the LHC distinguish between the SM light Higgs scenario, a composite Higgs and the Higgsless case using VV scattering channels?

TL;DR

This paper evaluates the LHC's ability to distinguish between the Standard Model light Higgs, composite Higgs, and Higgsless scenarios by analyzing vector boson scattering channels through detailed parton level simulations.

Contribution

It provides a comprehensive parton level analysis including all relevant processes to compare different Higgs scenarios at the LHC.

Findings

Potential to identify composite Higgs as an excess in boson-boson scattering events.

Comparison of infinite Higgs mass scenario with SM and composite Higgs models.

Analysis combining multiple channels for Higgs scenario discrimination.

Abstract

A complete parton level analysis of ll + four jets l = e,mu and 3lv + two jets production at the LHC is presented, including all processes at order $\ordEW$, $\ordQCD$ and $\ordQCDsq$ when appropriate. The infinite Higgs mass scenario, which is considered as a benchmark for strong scattering theories and is the limiting case for composite Higgs models, and one example of a model incorporating a Strongly Interacting Light Higgs are confronted with the Standard Model light Higgs predictions. This analysis is combined with the results in the lv + four jets channel presented in a previous paper, in order to determine whether a composite Higgs signal can be detected as an excess of events in boson--boson scattering.
