Abstract

We illustrate how the measurements of the CP asymmetries in B⁰_d,s-decays together with a measurement of Br(K_L→ π^∘νν) or Br(K⁺→ π⁺νν) and the known value of | V_us| can determine all elements of the Cabibbo-Kobayashi-Maskawa matrix essentially without any hadronic uncertainties. An analysis using the ratio x_d/x_s of B_d- B_d to B_s- B_s mixings is also presented.
