Abstract

The purpose of this thesis is to analyze the potential for measurements of Standard Model vector boson scattering to probe new physics lighter than the TeV scale. Supersymmetry (SUSY) is one example of a beyond the Standard Model theory that contains a dark matter candidate. The Minimal Supersymmetric Standard Model (MSSM) provides a well-developed framework to construct illustrative test cases. Various Bino-Wino models, simplified versions of the MSSM, are utilized to cover a range of chargino and neutralino masses. The lightest superpartner, a neutralino, is the dark matter candidate. Simulations are used to explore the potential impact of SUSY signals on the phase spaces used by ATLAS and CMS to measure opposite sign W boson scattering. Upper limits on the SUSY signals are obtained by comparing the SUSY predictions to results from experimental vector boson scattering measurements performed at the LHC by ATLAS and CMS. The limits are weaker than those obtained with direct SUSY searches ATLAS and CMS. Thus, light new physics of this subset of SUSY will not contaminate Standard Model opposite sign W boson scattering measurements.
