So many kaons...

I've been polishing up a final paper on kaons all day, so I'm a little low on energy (and time) at the moment. Instead, have prettier Feynman diagrams for the neutral kaon oscillations!


Both of these are second-order weak interactions, as I've mentioned before. They show the strangeness oscillations I mentioned previously, but it turns out to be way easier to calculate how much oscillation there by converting between strangeness and CP eigenstates. I still find the Feynman diagrams useful, though, since they give a concrete physical way for the strangeness of a kaon beam to evolve, in addition to the somewhat abstract mathematical approach.
