TL;DR

This paper investigates vector boson scattering at the LHC using unitarized models implemented in a six-fermion Monte Carlo simulation, comparing their predictions with other approximation methods and the no-Higgs scenario.

Contribution

It introduces a full six-fermion calculation of unitarized model predictions for vector boson scattering at the LHC, enhancing the accuracy of phenomenological studies.

Findings

Unitarized models provide distinct high-energy scattering predictions.

Comparison with Equivalent Vector Boson Approximation highlights differences.

Results inform experimental searches for strongly interacting symmetry breaking sectors.

Abstract

Unitarization models describe phenomenologically the high energy behaviour of a strongly interacting symmetry breaking sector. In this work, predictions of some unitarized models in vector boson scattering at LHC are studied and compared with analogous studies in Equivalent Vector Boson Approximation and previous results for the benchmark no-Higgs scenario. To perform such studies, unitarized model amplitudes have been implemented in the PHANTOM Monte Carlo in a complete calculation with six fermions in the final state.
