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:

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.
