Abstract: I will present an analysis of the 2011 LHC Higgs data in the context  of an effective low-energy theory of the Higgs boson. The focus will be on the 4-leptons and diphoton channels at the LHC and the  b-bar channel at the Tevatron. Combining the available data in these channels, one can  derive constraints on the effective theory parameters. These constraints can then be mapped several simplified scenarios  of natural new physics  capturing the Higgs physics of simple  supersymmetric and composite Higgs models.  I will also discuss the phenomenological  consequences of the assumption that the Higgs couplings to the electroweak gauge bosons is larger than in the Standard Model. The latter may be hinted at by the CMS diphoton channel excess in the dijet category, and by the Tevatron excess in the W/Z+H -> b-bar channel.
