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 ...

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 ...

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

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

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.

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 ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

What is meant, when an experiment anticipates less than a quarter of an event, and four are registered by the detector? That ...

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 ...

Neutrinos are known for funny business. Now scientists have set a new limit on a quantum trait responsible for the subatomic particles’ quirkiness: uncertainty. The lightweight particles morph from ...
