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 cumin chicken wings recipe

Present LHC Higgs coupling measurements suggest it is effectively point-like down to a length scale merely a factor three below the electroweak scale. It could still be very fuzzy indeed! As fuzzy as a pion. If so, hardly an SM-like Higgs!
