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.

Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place. Obviously that didn't happen. Experiments at the Large Hadron Collider (LHC) may ...

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.

For the first time, physicists have spotted a difference in the way matter and antimatter baryons decay, which could help to ...

Scientists study antimatter, investigating the ways in which it acts like ordinary matter and the ways in which it differs.

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

It took more than 80,000 baryon decays for us to see matter–antimatter asymmetry with this class of particles for the first time." Particles are known to have identical mass and opposite charges ...
