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 ...

Using some of the world's most powerful supercomputers, a group of theorists has produced a major advance in the field of nuclear physics—a calculation of the "heavy quark diffusion coefficient." This ...

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. Let’s take a look at why we ...

Our holiday gifts to our listeners are answers for all their wacky but fascinating science questions, like: Genevieve Willis from London ON asks: Is there any evidence to suggest that "getting cold" ...

The internal structure of a proton, with quarks, gluons, and quark spin shown. The nuclear force acts like a spring, with negligible force when unstretched but large, attractive forces when stretched ...

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...
