2000 CKM-triangle analysis a critical review with updated experimental inputs and theoretical parameters

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 |ɛ_k|, |V_ub/V_cb|, Δm_d and from the limit on Δm_s, available in September 2000. Results from the experimental search for B⁰_s-bar B⁰_s oscillations are introduced in the present analysis using the likelihood. Special attention is devoted to the determination of the theoretical uncertainties. The purpose of the analysis is to infer regions where the parameters of interest lie with given probabilities. The BaBar ``95% C.L. scanning" method is also commented.
