Quarks make up all matter, but have never been seen by themselves. And they have “flavors” and “colors” — though neither term has any relevance to what they actually do.

Deep within the atoms that make up our bodies and even within the protons and neutrons that make up atomic nuclei, are tiny particles called quarks. When you purchase through links on our site, we ...

Ever wondered what makes up the universe? Explore the fascinating world of fundamental particles, from the tiniest quarks to ...

Quarks, which make up protons and neutrons, are another type of fundamental particle. Together with the leptons, quarks make up the stuff we think of as matter.

Quarks and leptons are fermions — the elementary particles that make up matter. Another group of particles, known as bosons, act as "force carriers." That means they hold the forces that let ...

Up quarks have a +2/3 charge, and down quarks have a -1/3 charge. If you add and subtract those fractions, you get the +1 charge of a proton. Valence quarks get lots of attention.

Up and down quarks, for example, make up the protons and neutrons in the atomic nucleus. Beauty quarks are unstable, living on average just for about 1.5 trillionths of a second before decaying ...

— Using artificial intelligence software to analyze huge volumes of particle collider data, the scientists detected evidence of intrinsic charm quarks within protons. It makes up about 0.62 ...
