Research output: Contribution to journalArticlepeer-review


We calculate the complete set of O(GFMH2) corrections to the elastic scattering of longitudinally polarized W bosons in the limit s,MH2 MW2, for any value of s/MH2. For any Higgs-boson mass such that MH MW, there exists a critical energy above which partial-wave unitarity is violated and the one-loop correction to the J=0 partial wave is large, indicating the breakdown of perturbation theory.
