We study baryon-number-changing processes at high energy in electroweak theory. We find that at energies of the order of 10 TeV, some inelastic partial-wave amplitudes saturate the unitarity limit and the cross section for such processes becomes as large as ±w2MW2. We argue that at high energies, lepton interactions become strong with distributions of particles typical of strong-interaction processes. The multiplicity of particles in the final state is of order 1±w, the transverse momenta are of order MW, and the types of particles are primarily Higgs and gauge bosons and their decay products.
