Description
At present, there is a lack of experimental data constraining the dependence of the strange nucleon parton distribution functions (PDFs) on the parton momentum fraction and the electroweak mixing angle at low-$Q^2$. The parity-violating asymmetry from the neutral-current deep inelastic scattering of electrons from proton and deuterium targets, which will be measured by the proposed SoLID experiment at Jefferson Lab, possesses a known sensitivity to both the strange PDFs and electroweak parameters. In this work we explore this sensitivity and perform a new global analysis, incorporating pseudo-data from simulations based on SoLID experimental projections with radiative corrections to the asymmetry, for the unpolarized PDFs and the weak-mixing angle. We find a sizable constraining power of future $A_{PV}$ data on the high-$x$ behavior of the nucleon strangeness and a substantial resolving power on the weak-mixing angle at low-$Q^2$.
