Abstract

Why is our Universe made of matter and not antimatter? It might be explained if the laws that govern matter and antimatter are different. In 1964, matter-antimatter asymmetry was discovered in the weak decays of elementary particles called Kaons. At the KEKB B factory we have discovered CP violations in B meson decays and have thus established the Kobayashi-Maskawa model of CP violation. The present article reviews the history of CP violation, focusing on recent results from the B factories and prospects in this field.
