Abstract

We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from protons. Significant contributions to this asymmetry could arise from the contributions of strange form factors in the nucleon. The measured asymmetry isA=−15.05±0.98(stat)±0.56(syst)ppmat the kinematic point⟨θlab⟩=12.3°and⟨Q2⟩=0.477(GeV∕c)2. Based on these data as well as data on electromagnetic form factors, we extract the linear combination of strange form factorsGEs+0.392GMs=0.014±0.020±0.010, where the first error arises from this experiment and the second arises from the electromagnetic form factor data. This paper provides a full description of the special experimental techniques employed for precisely measuring the small asymmetry, including the first use of a strained GaAs crystal and a laser-Compton polarimeter in a fixed target parity-violation experiment.
