Constraints upon the CKM angle φ 2 from Belle and


The Standard Model predicts CP violation to occur in B meson decays due to a complex phase in the 3×3 Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix. This phase is illustrated by plotting the unitarity condition V ∗ ubVud + V ∗ cbVcd + V ∗ tbVtd = 0 as vectors in the complex plane: the phase results in a triangle of nonzero height. One interior angle of the… (More)
