Radiative corrections to longitudinal-vector-boson scattering

We calculate the one-loop radiative corrections of enhanced electroweak strength, $O\left(\frac{g^2{m}_H^2}{M_W^2}\right)$, to all 2→2 longitudinal-vector-boson scattering amplitudes in the limit $s$, $m_H^2\gg M_W^2$. We find that these corrections are positive and, for $m_H\approx 1$ TeV, significantly increase the cross section for vector-boson pairs with large invariant mass.
