Pionic helium In this experiment, a pion – shown here with one orange and one blue particle representing its quark and anti-quark – replaces one of the two electrons in the helium atom. This new ...

Pions are some of matter’s simplest particles. They’re built from the same building blocks as protons and neutrons, smaller particles known as quarks. While a proton is made from three quarks, only ...

Based on the lectures and discussions of historians and physicists at the Second International Symposium on the History of Particle Physics, held at Fermilab on May 1-4, 1985.

Physicists predicted the existence of the Higgs boson decades before its discovery in 2012 because of symmetries in the building blocks of our universe. Similarly, rules about a special type of ...
