Kobayashi-Maskawa matrix

The Kobayashi-Maskawa matrix, or CKM matrix, is a mathematical representation used in particle physics to describe how different types of quarks—fundamental particles that make up protons and neutrons—transform into one another via the weak force. This matrix is important for understanding processes like particle decay and how certain particles can change their characteristics. Its elements indicate the probability of one type of quark transforming into another, revealing insights into the behavior of matter and the differences between particles, which are key to explaining phenomena like why there is more matter than antimatter in the universe.
