Investigation of mass reconstruction techniques for resonances in the scattering of $W^{\pm}W^{\pm} \to W^{\pm}W^{\pm}$ at the LHC

Physics scenarios of electroweak symmetry breaking beyond the Standard Model introduce new resonances in the scattering of massive, weak gauge bosons. Due to the best signal to background ratio, the like-sign "W^{\pm}W^{\pm}"jj channel is the most favourable final state for a first glance at resonances in vector boson scattering (VBS) at a hadron collider such as the LHC. Resonances in this scattering process can be modelled with the approach of an effective field theory and the K-matrix unitarisation method. This thesis presents a study of mass reconstruction of resonances in the fully leptonic decay channel of like-sign "W^{\pm}W^{\pm}" scattering. Special emphasis lies on the technique of constrained minimisation leading to mass bound variables. For different resonance types, variables providing the best discovery potential in proton-proton collisions at a centre-of-mass energy of "\unit[8]{TeV}" and an integrated luminosity of "\unit[20]{fb^{-1}}" are determined and characterised.
