Abstract
The Higgs-boson line shape is studied within the pinch technique resum mation formalism. shown that to one-loop order in perturbation theory any resonant Higgs-boson amplitude contains a universal part which is gauge independent, renormalization-group invariant, satisfies the opti cal and equivalence theorems, and constitutes the natural extension of the QED effective charge to the case of the Higgs scalar.
