The Bs meson is a Meson noted for its ability to oscillate via a box-diagram between matter and antimatter with Δms=17.77 ±0.10 (stat) ±0.07 (syst) ps−1  (numbers from CDF at Fermilab). A first estimation of the lower and upper limit of this value have been found at the D0 experiment, also at Fermilab.
Additional recommended knowledge
On September 25, 2006, Fermilab announced that they had claimed discovery of previously-only-theorized Bs meson oscillation. According to Fermilab's press release:
This first major discovery of Run 2 continues the tradition of particle physics discoveries at Fermilab, where the bottom (1977) and top (1995) quarks were discovered. Surprisingly, the bizarre behavior of the Bs (pronounced "B sub s") mesons is actually predicted by the Standard Model of fundamental particles and forces. The discovery of this oscillatory behavior is thus another reinforcement of the Standard Model's durability. . . .
Ronald Kotulak, writing for the Chicago Tribune, called the particle "bizarre" and stated that the meson "may open the door to a new era of physics" with its proven interactions with the "spooky realm of antimatter".
