High-Energy Particle Collisions Research

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 $\ensuremath{\sigma}\ensuremath{\sim}\frac{{\ensuremath{\alpha}}_{w}^{2}}{{M}_{W}^{2}}$. 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 $\frac{1}{{\ensuremath{\alpha}}_{w}}$, the transverse momenta are of order ${M}_{W}$, and the types of particles are primarily Higgs and gauge bosons and their decay products.
