Calculates the asymmetry in nucleon-nucleon elastic scattering at high energies arising from heavy boson exchange in the standard Weinberg-Salam model. By neglecting the strong interaction enhancement effects, the authors' result for p-n scattering is one order of magnitude higher than for p-p scattering. Enhancement effects increase the p-p asymmetry, which may become comparable with the p-n asymmetry. Their asymmetries, however, are too small if compared with the total cross section asymmetry measured at Argonne at 6 GeV/c on a water target.
