CP violation is a phenomenon in particle physics where the laws of physics are not symmetric under the combined transformation of charge conjugation (C) and parity (P). This violation is observed in certain particles and interactions, particularly in the decays of neutral mesons such as kaons and B mesons. The study of CP violation is important for understanding the fundamental symmetries of the universe and the behavior of matter and antimatter. It can help explain why there is more matter than antimatter in the universe, a puzzle known as the matter-antimatter asymmetry problem. Researchers in the field of CP violation conduct experiments to measure the asymmetries in the decay rates of particles and search for new sources of CP violation. These studies provide valuable insights into the nature of particle interactions and could potentially lead to new discoveries in particle physics.
