The popular mechanics article was completely incomprehensible. Here's what I understood after a bunch of Wikipedia and reading the article's abstract: A pair of a quark and an antiquark combine to form an entity called a meson. If one of the pair is a strange quark (or a strange antiquark), that type of meson is called a Kaon. The standard model of physics makes predictions on how often a specific Kaon (K_L) will decay as: K_L→π0νν¯ KOTO is trying to measure this decay rate to see if it's in line with what the standard model predicts. They observed 4 such decays. 1 of them was identified as background noise. The other 3 decays are still an unexpectedly high number of decays. If there's a physicist in the room, please help verify my understanding.
