This thesis presents a measurement of the mass, natural width, and signal strength, defined as the yield normalized to the Standard Model prediction, of the Higgs boson in the H → ZZ(*) → 4&ell; decay channel using an approach which utilizes event-by-event detector response information. The measurement is performed on p-p collision data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The data corresponds to an integrated luminosity of 25 fb-1 with center-of-mass energies of 7 TeV and 8 TeV. The measured mass of the Higgs boson is mH = 124.57-0.43 +0.48 GeV. The signal strength was estimated at mu = 1.76-0.37+0.46. Finally, the natural width of the Higgs was determined to be < 2.6 GeV with 95% confidence. The event-by-event approach used in this analysis involves the parameterization of the behavior of single leptons in the ATLAS detector and the convolution of a mass response with the Higgs truth distribution to derive the reconstruction level signal model.
