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

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 ...

The proton packs were invented by two of the Ghostbusters, and not only look cool, but have a realistic scientific basis. The proton pack works as an unlicensed nuclear accelerator using carbon 14 and ...

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 ...

The proton, one of the most well-known and basic building blocks of matter, turns out to be holding on to a few secrets. A new measurement found that the radius of the proton is about 4 percent ...

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 ...

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.

Protons, among the building blocks of atoms, are even smaller than we thought—and the unexpected discovery may alter some of the most trusted laws of physics. All atoms are made up of nuclei orbited ...

Physicists at York University in Toronto have spent the last eight years meticulously conducting a sensitive experiment to measure the charge radius of the proton in hopes of resolving conflicting ...
