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.

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 ...

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 ...

The discovery of a new subatomic particle that may be the elusive Higgs boson has electrified the entire field of physics. The particle has... Scientists have discovered a new subatomic particle with ...

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 ...

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 ...

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 ...

New research suggests reported decays of a Kaon by the Koto experiment may actually be new particles. Florida State University physicists believe they have an answer to unusual incidents of rare decay ...

Quantum chromodynamics, or QCD, is the theory of the strong interaction between quarks and gluons. Lattice QCD uses supercomputers to explore 'tantalizing hints' of new physics in discrepancies ...
