Higgs and new physics at high energy

The observation of a new particle in the search for the Standard Model (SM) Higgs boson at the LHC, reported by the ATLAS and CMS collab- orations, is a milestone in the quest to understand electroweak symmetry breaking. The evidence for a Higgs boson-like particle has been pub- lished at the level of 5 σ by both experiments after preliminary analysis of the data from the LHC Run-I. Precision measurements of the new particle are of critical importance. This document reviews the mass and spin mea- surement, the couplings scale factor measurements using a state-of-the-art framework and the limits on new physics derived from these results.
