High energy proton-proton scattering is a cornerstone of modern particle physics, providing fundamental insights into the strong interaction and the structure of matter. At energies reached in ...

Quantum electrodynamics (QED) stands as one of the most rigorously tested theories in modern physics, offering a comprehensive framework to describe the interactions between charged particles and the ...

Physicists have begun to explore the proton as if it were a subatomic planet. Cutaway maps display newfound details of the particle’s interior. The proton’s core features pressures more intense than ...

Bottom: elastic proton scattering cross sections from oxygen-16 at different orders of magnitude. Credit: Charlotte Elster When atomic nuclei and subatomic particles interact, the results are ...

Getting an up-close view of life at the cellular level can be as simple as placing onion skin under a microscope and adjusting the knobs. Peering deeper, into the heart of the atoms within, isn't as ...

Sharper proton beams for safer and more effective treatment When used as a membrane to split molecular hydrogen ions (H 2+) into individual protons, UC-MAC produced proton beams that were ...

Top: protons striking a nucleus deflect from their original path depending on velocity, location of impact, and force from the protons inside the nucleus. Bottom: elastic proton scattering cross ...
