Interpreting the Higgs

The LHC and Tevatron Higgs data are interpreted as constraints on an effective theory of a Higgs boson with mass close to 125 GeV. We focus on the diphoton, ZZ*, WW* channels at the LHC, and the b-bbar channel at the Tevatron, which are currently the most sensitive probes of a Higgs with such a mass. Combining the available data in these channels, we derive the preferred regions of the parameter space of the effective theory. We further provide the mapping between the effective theory and the relevant Higgs event rates, facilitating future extraction of the preferred region by the ATLAS and CMS collaborations.
