Fits to the CKM matrix

Within the Standard Model, a review of the current determination of the sides and angles of the CKM unitarity triangle is presented, using experimental constraints from the measurements of vertical bar εK vertical bar, vertical bar Vub/Vcb vertical bar, Δmd and from the limit on Δms, available by summer 2000. Peculiar attention has been devoted to the determination of theoretical uncertainties. Results from the experimental search on B0s - B0s-bar oscillations are introduced in the present analysis using the likelihood ratio approach. Different fitting techniques have been compared
