Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

Researchers have made a precise measurement of the size of the proton -- a crucial step towards solving a mystery that has preoccupied scientists around the world for the past decade. The world's ...

Nonconformists could take a page from the proton’s playbook: The subatomic particle is once again resisting scientists’ attempts to size it up. Everyone agrees the proton is tiny: Its radius is less ...

Like a quantum version of a whirling top, protons have angular momentum, known as spin. But the source of the subatomic particles’ spin has confounded physicists. Now scientists have confirmed that ...

How many protons can dance on the head of a pin? The answer is nowhere near as straightforward as one may think — and it might offer new insights into one of the most well-tested theories in physics.

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 ...

How big is a proton? Unlike an electron or neutrino, which are fundamental particles that behave like points, a proton is a messy collection of quarks, gluons, and virtual particles that occupies what ...

DENVER — The size of a proton, long thought to be well-understood, may remain a mystery for a while longer, according to physicists. Speaking today (April 13) at the April meeting of the American ...

The Gyeongju Proton Accelerator, known as the 'Midas touch of modern science' for its ability to produce radioisotopes used in cancer diagnosis and alter the properties of materials, has surpassed ...
