dc.descriptionThe LEP investigation of the Bd and Bs oscillations and of the Cabibbo-Kobayashi-Maskawa matrix element Vub improve the constraints on the other elements of this matrix. From a fit to the experimental data and the theory calculations it is possible to determine the vertex of the unitarity triangle as: rho = 0.155 -0.105 +0.115 eta = 0.383 -0.060 +0.063. The corresponding values of its angles, in their customary definition in terms of sines for alpha and beta, are: sin(2 alpha) = 0.08 -0.50 +0.43 sin(2 beta) = 0.75 +/- 0.10 gamma = 68 +/- 15o. The fit also yields indirect information on the compatibility with zero of the CP violating phase of the matrix, on some non-perturbative QCD parameters and on the Bs oscillation frequency.
