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 ...

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.

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 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

Why did this particle mysteriously disintegrate?

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 ...

What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

Physicists working with the LHCb experiment at CERN have proven that a subatomic particle can switch into its antiparticle and back again. The researchers were able to prove this using extremely ...
