Vector-Vector scattering at the LHC with two charged leptons and two neutrinos in the final state

TL;DR

This paper performs a detailed analysis of vector boson scattering at the LHC, comparing the Standard Model with light and heavy Higgs scenarios, to identify potential experimental signatures of alternative Higgs models.

Contribution

It provides a comprehensive parton-level analysis of multiple channels at the LHC, including all relevant processes, to distinguish between Standard Model and alternative Higgs frameworks.

Findings

Standard Model and heavy Higgs scenarios show distinct scattering signatures.

Analysis constrains the detectability of strongly interacting light Higgs models.

Combined channel analysis enhances sensitivity to new physics in boson scattering.

Abstract

A complete parton level analysis of 2l2v2j and 4l2j, l = mu,e production at the LHC is presented, including all processes at order alpha^6, alpha^4*alpha_s^2. 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 Strongly Interacting Light Higgs models are confronted with the Standard Model light Higgs predictions. This analysis is combined with the results in the lv4j, the ll4j and the 3lv2j channels presented in previous papers, in order to determine whether these alternative Higgs frameworks can be detected as an excess of events in boson--boson scattering.
