Sumario:Vector boson scattering is an important process for understanding electroweak symmetry breaking. By measurements of this process, hints to physics beyond the Standard Model might be found and limits can be set. A model independent way of describing this physics are anomalous quartic gauge couplings. These describe the low energy tail of possible resonances. In this thesis the predicted relation between anomalous quartic gauge couplings and explicit resonances is studied based on Monte Carlo simulations. In this context two scalar isotensor resonances are studied in $W^{\pm} W^{\pm} \rightarrow W^{\pm} W^{\pm}$and a tensor isotensor resonance as well as a scalar isotensor resonance in $W^{\pm} Z \rightarrow . W^{\pm} Z$.
