Abstract

A complete parton level analysis of 2ℓ2ν2j and 4ℓ2j, ℓ = μ, e production at the LHC is presented, including all processes at order \( \mathcal{O}\left( {\alpha_{\text{EM}}^6} \right) \), \( \mathcal{O}\left( {\alpha_{\text{EM}}^4\alpha_{\text{S}}^2} \right) \). 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 ℓν + four jets, the ℓ − ℓ + + four jets and the 3ℓν + two jets 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.
