The CDF experiment at Fermilab has measured the oscillation of the Bs meson into Bs-bar. Quoted as a mass difference, the value is Delta_ms = 17.77 +- 0.10 (stat) +- 0.07 (sys) ps-1.

The oscillation is explained by the Standard Model, and the value above is in accordance with it. However, there are many beyond SM models (supersymmetry for instance) that cannot avoid affecting this oscillation. So this result will help narrow the window for new physics. The details are in hep-ex/0609040. Read more at the CDF Web site at FermiLab

Kitta MacPherson of the Newark Star-Ledger had a story this morning: http://www.nj.com/search/index.ssf?/base/news-9/1159251134290850.xml?starledger?ntop&coll=1

Note an egregious mistake near the end: "For reasons of physics, the Higgs boson, which has much less mass, would likely be drawn to the heavier b quark in the meson." Oh, don't we wish the Higgs were that light! In fact, the Higgs boson has much MORE mass than the b quark. It is (probably) lighter than twice the top quark mass, so it will want to decay to the LIGHTER b quark. Assuming of course the Higgs is indeed what is responsible for breaking electroweak symmetry.
