We know that all matter is composed of atoms, and atoms are made of protons and neutrons inside the nucleus and electrons outside. But unlike electrons, protons and neutrons are composite particles ...

Quarks are found in protons and are bound together by forces which cause all other known forces of nature to fade. To understand the effects of these strong forces between the quarks is one of the ...

Nowadays physicists are confident in their knowledge of nature’s ultimate bits of matter. A handful of building blocks can be easily summarized in a neat little chart. But merely half a century ago, ...

A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The calculations ...

Scientists have for the first time observed quantum entanglement — a state in which particles intermingle, losing their individuality so they can no longer be described separately — between quarks.

Newly discovered particles have incited a fierce debate among experts about the correct picture of matter at the quantum scale. In August 2003, an experiment at the KEKB particle accelerator in Japan ...

Takashi Kubota does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond ...

So there are these things called quarks. (I know, I wish they had a better name, but I'm not in charge of naming things in physics.) Quarks are little teensy tiny particles (we'll get to exactly how ...
