Physicists have struggled for seven decades with the question of why there is more matter in the universe than antimatter.

What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you, I'm ...

A team at CERN has reported the observation of a new type of particle made up of four quarks. This discovery could enhance our understanding ...

In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypothetical particle, known ...

Smashing atomic nuclei together at mind-bending speeds recreates the fiery conditions of the early universe and scientists are finally getting a better handle on what happens next. A sweeping new ...

Physicists at the ATLAS detector of the Large Hadron Collider (LHC) have spotted top quarks — the heaviest of all known elementary particles — that were produced by the collision of atomic nuclei 1.

Facilities that make particles called B mesons may seem obscure, but they could help explain why there is more matter than ...
