The internal structure of nucleons continues to be a major focus of both theory and experiment. This includes their makeup in terms of quarks and gluons, basic properties such as radii, as well as observables that serve as inputs for experiments that seek to constrain beyond-the-Standard-Model (BSM) physics. Here, we propose to calculate, among others, the charge radius of the proton, where there is disagreement between different experimental results on the 7-sigma level, and the scalar and tensor charges of the nucleon, which constrain possible BSM physics in the decay of ultra-cold neutrons.
