Abstract:
Both CMS and ATLAS Higgs searches have shown encouraging hints of a neutral resonance in the region around 125 GeV. In light of this, characterization of new resonances has become increasingly important. We present a strategy which, given a large amount of statistics, can be used to measure the couplings of an arbitrary spin zero, one, or two resonance to the standard model gauge fields. In the low statistics regime this method can be used to separate different hypotheses. We will show sensitivity projections of the latter given a standard model Higgs boson of mass 125 GeV decaying to two Z bosons and discuss the feasibility of incorporating other decay channels. Finally, we discuss future prospects for measuring the amplitudes and phases of different helicity contributions.
