The Tevatron collider at Fermilab provides a very rich
environment for the study of b-hadrons. One of the most important analyses
within the B physics program of the CDF experiment is B0(s) mixing. Since
the time this school was held, several improvements in the B0(s) mixing
analysis have made possible the measurement of the B0(s) oscillation
frequency, result that has been presented at the FPCP 2006 Conference. We
thank the organizers of the Corfu School for allowing us documenting here
these latest results.
