Will large weak interaction effects be observable at very high energies?

Abstract

We examine the possibility that some weak interaction cross section become larger at very high energies. Such effects could lead to observable weak interaction phenomena in very high energy pp and p p colliding beams. A part from direct production of W's and Z's, the possibility of observable weak effects requires the Higgs mass to be much larger than the mass of the vector bosons. However, for feasible experiments such effects are suppressed in many popular gauge theories, and we expect that observable weak cross sections will not get large at high energies. Theories with more than one Higgs boson may allow large observable effects.
