The CDF Collaboration at Fermilab has confirmed that a subatomic particle called the Bs meson flips between matter and antimatter about 3 trillion times per second, a measurement so precise it ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

Why did this particle mysteriously disintegrate?

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

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 ...
