TL;DR: These data represent the first measurement of the EMC effect for (3)He at large x and a significant improvement for (4)He and suggest that the nuclear dependence of the quark distributions may depend on the local nuclear environment.

TL;DR: In this paper, the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from protons was measured, and significant contributions to this asymmetry could arise from the contributions of strange form factors in the nucleon.
