CERN scientists found matter-antimatter asymmetry in baryons

Scientists at CERN have observed CP violation in baryons for the first time, a key step in understanding why matter dominates the universe over antimatter. This discovery provides crucial evidence of differing behavior between matter and antimatter. The LHCb collaboration at CERN's Large Hadron Collider found a significant difference in the decay rates of Λb⁰ baryons and their antiparticles, confirming CP violation. This finding, published in Nature, supports the idea that the universe's matter-antimatter imbalance stems from CP violation. This observation, while significant, doesn't fully explain the universe's matter dominance. Further research, including measuring the complex phase of the violation, is needed to compare the findings with the Standard Model and potentially uncover "new physics."
