WebAnd the total width (decay rate) around 170 GeV increases exactly because the Higgs decays to the WW final states start to become possible. Because the total width goes up, the ratio of a (non-WW) partial width and the total width goes down - and this ratio is what we call the branching ratio. Kostya wrote almost the same thing. WebThe width of such a distribution of mass energies is called the decay width Γ and is measured in units of energy. The decay width is related to the uncertianty in energy as follows. Γ = 2ΔE = ℏ τ = ℏλ where λ is the decay constant. However the Z-boson has many decay modes so this equation should be written as Γall = ℏλall
