Decay of the Higgs Boson via the H → Z* Z* → 4l Channel
Abstract
This paper investigates the decay of the Higgs boson through the H → Z* Z* → 4l channel. The decay amplitudes and widths are calculated, and the dependence of the decay probability on particle masses is examined. The study mainly focuses on the Higgs boson decay into four charged leptons. The decay probability is evaluated, and a graphical representation of the decay width as a function of the lepton mass is presented. The results demonstrate that the decay of the Higgs boson into heavy leptons, such as and , is highly suppressed.
