The success of the Kobayashi-Maskawa (KM) model of CP violation [1] in predicting correctly CP asymmetries in B meson decays has been recently recognized by the Nobel committee [2]. The large asymmetry measured in B → J/ψKS(L) [3, 4] given by sin 2β, where β ≡ φ1 = arg(−V ∗ cbVcd/V ∗ tbVtd), proved unambiguously that the KM phase is the dominant source of CP violation in B decays. This test inv...
