In July 2012 the discovery of a new boson with a mass of about 125 GeV and properties in agreement with those expected for the Higgs boson in the Standard Model was announced.In this note, we review the results of the search for the Higgs boson and the study of its properties performed with the proton-proton collision data recorded by the ATLAS and CMS detectors at the LHC in 2011 and 2012, corresponding to an integrated luminosity of 5 fb -1 and 20 fb -1 per experiment at √ s = 7 TeV and √ s = 8 TeV, respectively.The presented study confirms the Higgs-like nature of the new boson, with a signal rate consistent with the expectation of the Standard Model, and with the scalar nature of the new boson clearly favoured.In addition, we present studies of the diboson production as an example of a precise electroweak measurement at the LHC.The result, being in agreement with standard model predictions, is interpreted in terms of constraints on anomalous triple-gauge boson couplings.
