Abstract:
We report new measurements of the parity-violating asymmetry A(PV) in elastic scattering of 3 GeV electrons off hydrogen and 4He targets with =0.077 GeV2, and G(E)(s)+0.09G(M)(s)=0.007+/-0.011+/-0.006 at
=0.109 GeV2, providing new limits on the role of strange quarks in the nucleon charge and magnetization distributions.
