Abstract

From calculations of the

K_{L} - K_{S}

mass difference and

CP

nonconservation based on an effective quark Lagrangian, we limit the ranges of the charged-weak-current mixing angles

θ_{2}

and

θ_{3}

, and phase parameter

δ

. The relative strength of

b \to u

and

b \to c

couplings is determined versus

θ_{3}

.
