Why is there more matter than antimatter? CERN result offers tantalising new clue

For the first time, physicists have observed a particle of matter in the proton family behave fundamentally differently to its antimatter twin, which could help to explain why matter is so abundant in the Universe compared with antimatter. Researchers spotted subtle differences between the decay rates of a particle called the beauty-lambda baryon and its antimatter counterpart into other products. The findings fit with behaviours predicted by the standard model of particle physics, but provide a new hunting ground to look for unknown causes of the imbalance.
