New determination of quark mixing angles and phase

The Kobayashi-Maskawa angles and phase are determined with accuracy using recent B meson lifetime measurements together with the CP violation parameters of the K⁰ system. We get 0.032?sinθ₂?0.125, 0?sinθ₃?0.06, 140°?δ?179° (δ in the second quadrant). some implications, namely possible large B⁰-$\text{B}$⁰ mixing, are discussed.
