LHCb Observes New Antimatter Asymmetry
2025-07-21
The LHCb experiment at the Large Hadron Collider has observed a new difference between matter and antimatter in baryons, marking the first observation of CP violation in this type of particle. This discovery is a significant step towards understanding the universe's matter-antimatter imbalance. While the observed CP violation aligns with the Standard Model, it's insufficient to explain the cosmic asymmetry, suggesting the existence of undiscovered particles or new physics beyond the Standard Model.
