Charge-parity violation is thought to explain why there’s more matter than antimatter in the universe. Scientists just spotted it in a new place.

While it was expected that the other main class of known particles—baryons, which are made up of three quarks—would also be ...

Physicists have made a landmark discovery, uncovering the first clear evidence that matter particles, known as baryons, ...

Scientists at CERN have made a groundbreaking discovery that deepens our understanding of why the Universe is made of matter ...

Physicists have, for the first time, seen a matter particle from the proton family behave in a fundamentally different way from its antimatter twin. The finding — which fits with behaviours predicted ...

The CMS collaboration at CERN has observed an unexpected feature in data produced by the Large Hadron Collider (LHC), which ...

A key difference has been observed in the behaviour of matter and antimatter particles by researchers working at a particle ...

(via Fermilab) Scientists study antimatter, investigating the ways in which it acts like ordinary matter and the ways in which it differs. Antimatter is the opposite of ordinary matter and, when ...

Antimatter — the mysterious substance that's the mirror opposite of matter in most ways — falls downward in gravity like everything else in the universe, a team of physicists reported ...
