An up-to-date determination of the CKM matrix elements and of the unitarity triangle on the basis of the available experimental results
1999
The results of a critical review of the experimental sources that provide information on the CKM matrix are presented. Direct determinations of the matrix elements and indirect constraints (B-meson mixing, CP violation measurements,b →sγ Penguin decays) updated taking into account the most recent experimental results are included in a unitarity-constrained fit to determine the shape of the unitarity triangle. The following best values are found for the parameters describing the observable CP asymmetries which are expected inB decays: sin2α = −0.11+0.20-0.22, sin2β = 0.725+0.044-0.046, γ = (63.7+5.3-7.0)°.
