Contribution

It provides a detailed simulation framework for weak-boson scattering at the LHC, highlighting the distinctive signatures of new resonances and confirming the perturbative approach's reliability.

Findings

Models with new resonances produce distinctive lepton distributions.

Perturbative calculations of signal processes are highly reliable.

The study demonstrates the LHC's potential to probe strong interactions in the weak sector.

Abstract

We explore the potential of the CERN-LHC to access strongly interacting gauge boson systems via weak-boson scattering processes with W+W-jj, ZZjj, W+Zjj and W-Zjj final states, focusing on the leptonic decay modes of the gauge bosons. Cross sections and kinematic distributions for two representative scenarios of strong interactions in the weak sector and all relevant background processes are computed with fully-flexible parton-level Monte-Carlo programs that allow for the implementation of dedicated selection cuts. We find that models with new resonances give rise to very distinctive distributions of the decay leptons. The perturbative treatment of the signal processes is under excellent control.
