This thesis describes the stand-alone discovery and dimension of the Higgs boson in its decays to 2 W bosons utilizing the Run-I ATLAS dataset. this can be the main distinct size of gluon-fusion Higgs boson construction and is one of the most vital effects attained on the LHC. The thesis presents an extremely transparent exposition on a classy research played by means of a wide group of researchers. features of the research played by means of the writer are defined intimately; those contain new equipment for comparing uncertainties at the jet binning utilized in the research and for estimating the history because of linked construction of a W boson and an off-shell photon. The thesis additionally describes a dimension of the WW pass part, a vital historical past to Higgs boson creation. the first motivation of the LHC was once to turn out or disprove the lifestyles of the Higgs boson. In 2012, CERN introduced this discovery and the ensuing ATLAS ebook contained 3 decay channels: gg, ZZ, and WW.
