After the discovery of a new particle at the LHC, it is crucial to verify or disprove whether it is the SM Higgs boson. Thus, its features, including its spin, have to be determined. In order to distinguish between spin-0 and spin-2, light spin-2 resonances are studied. Since the SM Higgs boson ensures the unitarity of vector-boson scattering, another topic is to investigate if other particles are able to perform the same task. Furthermore, heavy spin-2 resonances at the LHC are studied.
