When they do, they pass one last flurry of national health care and other social programs. The analogy of this type of CP violation is that Republicans occasionally morph into Democrats, who then pass more social programs. A Rarer Decay Physicists can distinguish between the two effects, because the debris that cascades outward when a kaon decays differs slightly depending on the type of CP violation. Or, concluding the political analogy, the social programs passed by Republicans are different than those passed by Democrats. The 1964 effect occurs only once per 500 kaons.
Theorists have much to ponder.
On the one hand, the value found by the Fermilab is larger than is predicted by standard models of physics. On the other hand, it is far too small to explain the matter-antimatter disparity. That suggests something else in the universe is also violating CP, perhaps an as-yet undiscovered force. The CERN particle physics laboratory in Switzerland is currently analyzing data from a similar experiment, and twoexperiments looking for CP violation in particles called B mesons will start running later this year. Whatever the causes, without CP violation, you'd never be around to read this article about CP violation.
