Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ ...

In collisions of argon and scandium atomic nuclei, scientists from the international NA61/SHINE experiment have observed a clear anomaly indicative of a violation of one of the most important ...

In a never-before-seen particle, four quarks of a feather flock together. Physicists think they have detected the first conglomerate of four quarks incorporating more than two of the same kind. This ...

The universe has cooked up all sorts of bizarre and beautiful forms of matter, from blazing stars to purring cats, out of just three basic ingredients. Electrons and two types of quarks, dubbed “up” ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Physicists at Cern have discovered a plethora of new exotic particles being created in the collisions produced by the Large Hadron Collider over the past few years. So many have been found, in fact, ...

After years of failed searches, CERN has finally caught a needle in a subatomic haystack: a heavy relative of the proton called Ξcc⁺. Ξ (or Xi) is a Greek letter pronounced like the word “Zye” (rhymes ...
