The Department of Energy’s Fermi National Accelerator Laboratory near Chicago. If accurate, it’s a sign that the theories forming the foundation of modern particle physics don’t tell the whole story.

Observations of extremely rare subatomic particle actions have allowed scientists to put one of the most stringent limits yet on the reigning theory of particle physics. Physicists at the world's ...

New research from the Fermi National Accelerator Laboratory (FermiLab) in Illinois has found that a tiny subatomic particle appears to be disobeying the laws of physics, which could open up a host of ...

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 ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

A decade ago, the Large Hadron Collider, Earth's most powerful particle accelerator, proved the existence of an subatomic particle called the Higgs boson -- thought to be a fundamental building block ...

The Muon g-2 ring sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the ...

At a lab in Batavia, Illinois, 200 physicists from seven countries have possibly made the biggest scientific discovery in decades. It involves a subatomic particle called a Muon. It's kind of like an ...
