Explore the fascinating world of proton physics in this 33-minute plenary session talk from the APS April Meeting 2015. Delve into the puzzling nature of protons as relativistic many-body systems and their role in understanding strong interactions and quantum chromodynamics. Learn about the proton mass puzzle, the European Muon Collaboration's discovery regarding quark contributions to proton spin, and the recent controversy surrounding proton charge radius measurements. Discover ongoing efforts to solve these mysteries and gain insights into nuclear physics, the structure of matter, and the incomplete understanding of nucleon spin. Examine topics such as generalized parton distributions, deep virtual Compton scattering, and parity-violating electron scattering. Conclude with an introduction to the Electron Ion Collider and its potential to advance our understanding of proton spin and hadron structure.
