Observability of large weak interactions at very high energies

The possibility is examined that some weak interaction cross sections become large at very high energies. Such effects could lead to observable weak interaction phenomena in very high energy pp and p anti p colliding beams. Apart from direct production of W's and Z's, the possibility of observable weak effects required 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 it is expected that observable weak cross sections will not get large at high energies. Theories with more than one Higgs boson may allow large observable effects. However, it may soon be possible to rule out such theories on the basis of new experimental data and more detailed phenomenological analyses now in progress. Also discussed is how to experimentally identify weak interaction effects at the very high energy colliding beam machines. The method consists of the detection of parity violating effects in the production of hadron resonances. Numerical results indicate that such effects due to the production of W's and Z's should be observable at Isabelle energies. Observation of such effects may be the best method to establish that new behavior of cross sections is not hadronic in origin. By observing hadron resonances with different quantum numbers, it is possible to study the flavor dependence of high energy weak effects; the energy dependence of the phi/π ratio may even be a useful signal of W production. In addition, weak interaction cross sections are calculated for the scattering of polarized beams. The possibility of observing unconventional kinds of weak interactions is briefly considered
