Protons are tiny yet they carry a lot of heft. They inhabit the center of every atom in the universe and play a critical role in one of the strongest forces in Nature. And yet, protons have a ...
During a deeply inelastic collision with a proton, a relativistic electron (highlighted in blue) can emit a high-energy photon (purple here) that penetrates interior of the proton, where it ‘sees’ ...
Scientists have used high-energy particle collisions to peer inside protons, the particles that sit inside the nuclei of all ...
A number of advanced energy technologies—including fuel cells, electrolyzers, and an emerging class of low-power electronics—use protons as the key charge carrier. Whether or not these devices will be ...
