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

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

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

With the discovery of the charm quark in 1974, there opened a new era of studying the heavy quark in the particle physics. Up to now, the Standard Model (SM) has been widely recognized as the theory ...

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 ...

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 ...

After years of failed searches, CERN has finally caught a needle in a subatomic haystack: a heavy relative of the proton ...

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, ...

Researchers at Tel Aviv University and the University of Chicago have shown that a huge amount of energy, with a reaction potential to release eight times as much energy as the individual fusion ...
