Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

Add Yahoo as a preferred source to see more of our stories on Google. For decades, physicists have relied on the principle of symmetry to simplify and understand the complex behaviors of subatomic ...

Researchers at CERN have announced a new particle that is like a slightly heavier version of the proton. This new particle, reported by the LHCb experiment, has two charm quarks and one down quark, ...

The new particle, named Xi-cc-plus, carries two heavy charm quarks and is about four times heavier than an ordinary proton.

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 ...

The Large Hadron Collider has discovered a new particle, the 80th identified so far by the world's most powerful particle ...

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 ...

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, ...

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 ...

Interior of the Projectile Spectator Detector (PSD) used in the NA61/SHINE experiment at CERN. In collisions of argon and scandium atomic nuclei, scientists from the international NA61/SHINE ...
