Nonstandard neutral weak boson and elastic electron-proton scattering

Journal Article · · Phys. Rev. D; (United States)

The prospect of using a precision measurement of parity violation in elastic electron-proton scattering in the GeV range to detect manifestations of the nonstandard neutral weak boson Z'/sup 0/ is investigated in some detail. The numerical results indicate that, for an assumed Z'/sup 0/ mass of about 300 GeV, the deviation of the predicted parity-violating beam and target asymmetries from those given by the standard Glashow-Weinberg-Salam electroweak theory can be in the vicinity of several percent. Thus, confirmation of the standard model to within an accuracy of a couple of percent in such measurement should yield a severe constraint on the possible existence of the nonstandard neutral weak boson.
