Abstract
We discuss the lineshape of a heavy Higgs boson, and the behaviour wel l above resonance. Previous studies concluded that the energy-dependen t Higgs width should be used in the resonance region, but must not be used well away from it. We derive the full result and show that it smo othly extrapolates these limits. It is extremely simple, and would be straightforward to implement in existing calculations.
