Recently, the ATLAS and CMS collaborations have announced the discovery of a 125 GeV particle, commensurable with the Higgs boson. We analyze the 2011 and 2012 LHC and Tevatron Higgs data in the context of simplified new physics models, paying close attention to models which can enhance the diphoton rate and may or may not allow for a natural weak-scale theory. Combining the available LHC and Tevatron data in the ZZ* 4-lepton, WW* 2-lepton, diphoton, and b-bbar channels, we derive constraints on an effective low-energy theory of the Higgs boson. We map several simplified scenarios to the effective theory, capturing numerous new physics models such as supersymmetry, composite Higgs, a dilaton, and an additional scalar, fermion, or vector boson. We further study extended Higgs sectors which naturally enhance the diphoton rate. We find that the data is consistent with the Standard Model Higgs and consequently, the parameter space in all models which go beyond the Standard Model are highly constrained by the available data.
