Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Matter is built around quarks, forming the nuclei of the atoms and molecules. While there are six types of quarks, regular matter contains only two: up quarks and down quarks. Protons contain two ups ...

The mysterious dark matter that makes up most of the matter in the universe could be composed, in part, of invisible and nearly intangible counterparts of atoms, protons and electrons, researchers say ...

A new way to study quarks, one of the building blocks of the protons and neutrons that make up atomic nuclei, is proposed. This has never been done before and doing so would help answer many ...

A major new finding about the fundamental structure of all matter has just been published by a group of researchers that includes a Temple University physicist and two former Temple graduate students.

Objects are made of atoms, and atoms are likewise the sum of their parts—electrons, protons, and neutrons. Dive into one of those protons or neutrons, however, and things get weird. Three particles ...

If you want to explain what was and what is, you need particle physics. Because everything we see consists of molecules and atoms, and atoms in turn consist of atomic nuclei and electrons. The atomic ...
