What Are the New Insights from Bs - Anti-Bs Mixing Measurements at Fermilab?

[selfAdjoint]

Has anybody seen the news on the new measurements of the Bs - anti-Bs mixing amplitudes by the D0 and CDF experiments at Fermilab?

Tommaso Dorigo has a scholarly description at http://dorigo.wordpress.com/2006/04/11/more-details-on-bs-mixing/" (you may have to scroll down to April 19 there; he doesn't seem to have permanent links).

An excerpt from Dorigo's essay:

From that determination, a very precise value of the ratio between the two elements of the Cabibbo-Kobajashi-Maskawa mixing matrix Vtd and Vts can be obtained: CDF finds |Vtd|/|Vts| = 0.209 +0.005 -0.008.

I think I may have missed the seminar on this by one of the PI a couple of weeks ago here. In any case, the Physics World report on this can also be found here.
