Abstract

Nucleons (protons and neutrons) have been extensively studied over the past 30 or 40 years, but our knowledge of their internal structure remains rather limited, largely because the nucleon's constituents, the quarks, are so tightly bound that the nucleon cannot be taken apart. As Rosner discusses in his Perspective, scattering experiments are providing increasingly detailed information about the spatial distribution of charges, spins, and currents within the nucleon. He highlights the work by Hasty et al., which goes a long way toward determining the role of "strange" quarks, originally thought not to play a role in ordinary matter.
