Abstract

We produce the light-front wave functions (LFWFs) of the nucleon from a basis light-front quantization approach. We employ the LFWFs to evaluate the electroweak form factors, and the valence quark unpolarized and polarized PDFs. Our predictions for the axial and tensor charges are comparable with the recent results from the recent lattice QCD simulations. The electromagnetic radii of the proton and the axial radius are in excellent agreement with the measurements.
