Researchers at CERN’s Large Hadron Collider in Switzerland recently detected a vanishingly rare particle they believe was around at the very

The rare tetraquark is one of dozens of nonelementary particles discovered at the accelerator and could help test theories about the strong nuclear force

In the world of quantum physics, things are different: quantum particles can be entangled, in which case they can no longer be regarded as independent individual objects, they can only be described as one joint system. For years, it has been possible to produce entangled photons - pairs of light particles that move in completely different directions but still belong together. Spectacular results have been achieved, for e...

Meyrin, Switzerland, sits serenely near the Swiss-French border, surrounded by green fields and the beautiful Rhône river. But a hundred meters beneath the surface, protons traveling at nearly the speed of light collide and create spectacular displays of subatomic fireworks inside the experimental detectors of the Large Hadron Collider at CERN, the European particle...
