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 ...

In the world of particle physics, you are never alone — quite literally. Every moment there is an invisible rainstorm of subatomic particles falling down on us from space. Unlike the kind of matter we ...

One of the most important observations in particle physics was the discovery in 1964 of the Omega-minus baryon at Brookhaven National Laboratory. In the two decades leading up to this point over 27 ...

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 ...

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 ...

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’ ...

There's been a persistent question that has plagued physicists for years — why are we made of matter and not antimatter? Now, a team of scientists working in Japan believe they may be close to ...

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.

The world of the teensy-tiny, the quantum realm, could have a favorite flavor. We're not talking about itty-bitty ice cream cones, of course. The world of particles is split into three camps, called ...
