Abstract: (APS)

We show that the quark mixing matrix can be parametrized in exactly unitary forms with the imaginary parts present only at the order of 10−3. With sx=s1 and sy well determined, measurements of ε′ or other CP-nonconservation effects can determine szsφ. Then after |Vub|≃sz is measured, sφ is known. We also give a simple expression for the CP asymmetry in the B0−B0 mixing.
