Perplexingly, the amount of CP violation predicted by the Standard Model is many orders of magnitude too small to account for the matter–antimatter asymmetry observed in the universe.

Scientists are exploring the possibilities of antimatter propulsion as they try to achieve interstellar travel. While conventional rockets provide high thrust, they struggle with low efficiency.

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...
