kaon decay (IMAGE) DOE/Brookhaven National Laboratory Caption A new calculation performed using the world's fastest supercomputers allows scientists to more accurately predict the likelihood of two kaon decay pathways, and compare those predictions with experimental measurements. The comparison tests for tiny differences between matter and antimatter that could, with even more computing power and other refinements, point to physics phenomena not explained by the Standard Model.
