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.

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 ...

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 ...

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

Why matter dominates over antimatter in our universe has long been a major cosmic mystery to physicists. A new finding by the world's largest particle collider has revealed a clue.

CERN scientists have built a 3840 MPixel detector using mobile camera sensors to track antihydrogen's fall in gravity. This ...

Perplexingly, the amount of CP violation predicted by the Standard Model is many orders of magnitude too small to account for ...

When a particle is hit by a force, that should destroy it. Instead ... At a basic level, we don’t understand how—if matter and antimatter are generated and thrown apart in equal measure ...

Things such as, air, water and rocks are all examples of matter. Antimatter is like the opposite of matter, made up of particles that have the opposite electrical charge. For example, matter has ...

(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 ...

In most ways matter and antimatter particles are symmetrical, which means the processes that bring one into being, or destroy it, create or remove equal amounts of the other. For the universe we ...
