The muon—the short-lived cousin of the electron—could be the key to understanding relationships between other fundamental particles. And it holds a mystery all its own. In the 1930s, scientists ...

Figure 1: Calculations incorporating a complete set of Feynman diagrams give the most accurate estimates of the anomalous magnetic moment of the electron and the muon to date. The most accurate theory ...

As researchers across the United States—and around the world—plan two new supersymmetry-hunting experiments to be located at Fermilab, symmetry writer Joseph Piergrossi sat down with collaborators ...

Imagine waking up one morning to find that your meter stick had shrunk, overnight, by exactly four centimeters. That difference sounds small, yet it is still dramatic enough to thoroughly muck up ...

Using a beam shot through the Earth's crust, physicists have found the first direct proof of a metamorphosis between two of the three known types of neutrinos — those known as ‘muon’ and ‘tau’ ...

According to a study published in the journal Nature, large space was discovered within the Great Pyramid in Egypt, the first major one since the 19th century. Using an imaging method called muon ...

The particle collider at CERN will soon restart. “There could be a revolution coming,” scientists say. By Dennis Overbye In April, scientists at the European Center for Nuclear Research, or CERN, ...

Editor's Note: This story was updated on Friday Sept. 11 at 2:45 p.m. E.T. Trouble is brewing in the orderly world of subatomic physics. New evidence from the world's largest atom smasher, the Large ...

Highly energetic: visualization of the light gathered from the 2.6 PeV event in IceCube. The image shows a portion of the vertical strings of photomultipliers that make up the detector array.
