Title: "Review of electroweak fits of the SM and beyond, after the Higgs discovery — with Gfitter"

Abstract:
In light of the discovery of the Higgs-like boson by the ATLAS and CMS Collaborations at the LHC, we present an update of the global Standard Model (SM) fit to electroweak precision data. Assuming the new particle to be the SM Higgs boson, all fundamental parameters of the SM are known, allowing for the first time to overconstrain the SM at the electroweak scale and assert its validity. We present and discuss the SM predictions of several key observables of the electroweak fit, which are dramatically improved by the knowledge of the Higgs mass. These results are compatible with, and exceed in precision, the direct measurements. Constraints from the electroweak fit on loop contributions from beyond-SM models are also obtained, through an analysis of the so-called oblique parameters. We discuss the impact of the electroweak fit on Higgs coupling studies and vice versa.
