The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

A committee-supported project or activity that has been completed and for which output dissemination has begun. Its committee has been disbanded and closeout procedures are underway. Elementary ...

Developed in the 1980s and has been used in state-of-the-art particle physics for over 30 years since then, the software ' FORM ' is becoming obsolete, and if it becomes unusable, it will be a painful ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. For particle physicists, this was ...

A scientific experiment has produced evidence researchers believe points to a previously undiscovered fundamental force of physics. All interactions in the natural universe - from a hand catching a ...

The Higgs boson, which was predicted nearly fifty years ago, is the elementary particle needed to explain why and how particles have mass. The ‘Standard Model’ of particle physics, which describes how ...

The Large Hadron Collider is going to be shut down — not permanently, but for a pretty long time — and the famous atom ...

Scientists are closing in on identifying a new force of nature after observing the peculiar 'wobble' of a subatomic particle. The experts whizzed tiny muons, which are similar to electrons, through a ...
