Abstract

The observation of a new particle in the search for the Standard Model Higgs boson by the ATLAS and CMS experiments [1, 2], with the LHC Run 1 data at center-of-mass energies of \(\sqrt{s}=7\) and 8 TeV, has been a major step towards the understanding of the mechanism of electroweak symmetry breaking [3, 4, 5]. As already illustrated in Sect.  2.4, the mass of the Higgs boson obtained from the combination of the ATLAS and the CMS Run 1 measurements is \(125.09 \pm 0.24\) GeV [6]. Measurements of the spin, parity and couplings of the new particle have shown no significant deviations from the predictions for the SM Higgs boson [7, 8, 9, 10]. With the increased center-of-mass energy and higher integrated luminosity of the Run 2 LHC data, the Higgs boson properties can be measured with higher accuracy.
