Using the first new method in half a century for measuring the size of the proton via electron scattering, scientists have produced a new value for the proton's radius in a new experiment. Using the ...

Inside the most powerful particle colliders on Earth, protons slam together at nearly the speed of light, shredding matter ...

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 ...

The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured ...

The horizontal axis represents the proton scattering angle and the vertical axis represents the ease with which protons are scattered. C-type and S-type are theoretical values assuming cluster and ...

Puzzling protons: Alexey Grinin and Dery Taray working on the vacuum system of the 1S-3S experiment at the Max Planck Institute for Quantum Optics. (Courtesy: MPQ) A new and extremely precise ...

Why were so many physicists so wrong about the size of the proton for so long? As Edwin Cartlidge explains, the solution to this “proton radius puzzle” has as much to do with bureaucracy and politics ...

A long-awaited experimental result has found the proton to be about 5% smaller than the previously accepted value. The finding has helped to prompt a redefinition of the particle’s official size and ...

The three valence quarks of a proton contribute to its spin, but so do the gluons, sea quarks and antiquarks, and orbital angular momentum as well. The electrostatic repulsion and the attractive ...

A new atom-thin carbon membrane developed at the National University of Singapore could transform proton beams for cancer therapy and boost next-gen energy devices, electronics, and molecular ...
