The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in ...

In the time it takes you to read this sentence, the Large Hadron Collider (LHC) will have smashed billions of particles ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same ...

Quantum electrodynamics (QED) is the most rigorously tested quantum field theory of the standard model of particle physics 1. It describes the fundamental electromagnetic interactions of particles and ...

Here’s what you’ll learn when you read this story: For nearly a century, the magnetic anomaly of the fundamental particle known as a muon has served as a means to test theories against experimental ...

The Muon g-2 Collaboration has doubled the precision of their 2021 measurement of the muon’s magnetic moment and it disagrees with the predictions based on the standard model of physics. Muons are ...

Red lines show the disintegration of a B-sub-s into two muons in the CMS camera at the Large Hadron Collider. Yello, green and blue are used to denote particles other than muons. Purdue University ...

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 ...

The standard model of particle physics is often illustrated as a simple grid showing the 17 basic particles (shown above). But an alternative way of visualising it reveals the complex rules that ...
