Kaons are a type of meson that contain a strange quark and are known for their role in the study of particle physics, particularly in understanding the weak interaction. They come in several varieties, including charged kaons (K+ and K-) and neutral kaons (K0), and are significant for their unique properties, such as their relatively long lifetimes compared to other mesons and their involvement in CP violation, which is crucial for explaining the matter-antimatter asymmetry in the universe.
congrats on reading the definition of Kaons. now let's actually learn it.
