Strength of Weak Interactions at Very High Energies and the Higgs Boson Mass

It is shown that if the Higgs boson mass exceeds ${M}_{c}={(8\ensuremath{\pi}\frac{\sqrt{2}}{3{G}_{\mathrm{F}}})}^{\frac{1}{2}}$ partial-wave unitarity is not respected by the tree diagrams for two-body reactions of gauge bosons, and the weak interactions must become strong.
