In its first moments, the infant universe was a trillion-degree-hot soup of quarks and gluons. These elementary particles ...

CERN’s Large Hadron Collider (LHC) is designed to probe the fringes of known physics, and now the facility has found particles not behaving as predicted. While it’s still early days, the discovery ...

Scientists from the CMS collaboration at CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to understanding how matter behaved in the very early ...

CERN’s Large Hadron Collider will soon be smashing oxygen and neon atoms into other atoms of their own kind as part of its ATLAS experiment. The collisions will happen under enough heat and pressure ...

Physicists at CERN have discovered an exotic new particle that’s quite charming. Known as T cc +, the particle belongs to a rare class called tetraquarks, and its unusual composition makes it the ...

Scientists working at CERN's Large Hadron Collider Beauty (LHCb) experiment announced that they have finally figured out the structure of an exotic particle known as the pentaquark, meaning a group of ...

Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world's most powerful particle ...

The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top quarks that suggests that these heaviest of all elementary particles form a ...

Why didn’t the universe annihilate itself moments after the big bang? A new finding at Cern on the French-Swiss border brings us closer to answering this fundamental question about why matter ...
