Unitarity Triangle from CP invariant quantities
K. Kleinknecht, B. Renk
Abstract
We construct the CKM unitarity triangle from CP invariant quantities, using the coupling constant of weak decays with flavor change from b to u, and the particle - antiparticle mixing probability in the Bs and Bd systems. Also included are new measurements of the coupling Vus in Kaon decays. Of the two solutions, one agrees perfectly with the triangle constructed from CP violating processes in the K and B meson systems. The common solution yields a triangle with an area of J/2 = (1.51 +/- 0.09) x 10-5 and a CP violating phase gamma = 63.1o +/- 4.0o.
