dc.description.abstract | This thesis presents and discusses measurement of effective field theory couplings of the Higgs boson to weak vector bosons. The analysis uses data collected during the LHC Run 2 data taken at sqrt(s) = 13 TeV by the ATLAS detector corresponding to a total integrated luminosity of 36.07 fb−1. The measurement focuses on the gluon fusion production mode, targeting H → W±W∓∗ → l−ν ̄ll′+νl′ decays. The SM Higgs boson observed signal strength was measured as μ = 1.258+0.208−0.200 with an observed and expected significance of Zobs. = 6.6σ and Zexp. = 5.3σ. With the use of an Effective Lagrangian Morphing interpolation technique a CP-even and a CP-odd Higgs to W boson effective coupling parameter was measured. Both the signal strength and effective coupling parameter measurement show no significant deviation from the Standard Model. | |
