More than a kilometer underground, in what used to be a gold mine, inside a tank filled with tons of liquid xenon, “something” struck the nucleus of an atom. The tiny collision left an unusual energy ...

While it’s only a one-off event and below the statistical threshold for researchers to claim detection, the results are in ...

The particle zoo just got even stranger. Physicists searching for an elusive exotic particle instead found evidence of two unexpected structures that do not fit neatly into the familiar picture of ...

Many people are aware that the Large Hadron Collider (LHC) at CERN smashes tiny subatomic particles together at nearly the speed of light to test foundational laws of physics and discover new ...

The Universe is like water flowing downhill, and that's not a New-Age-style spiritual mantra. Particles and systems spontaneously move to lower energy states, including heavy particles decaying into ...

After almost two decades of searching, a team of physicists in China says it has observed strong evidence of a mysterious particle called a glueball, which is made entirely of force-carrying particles ...

"Collisions where objects bounce off perfectly, like billiard balls" and "collisions where objects like mud balls hit and stick together"—what is the difference between these two in the world of ...
