Strange B mesons are noted for their ability to oscillate between matter and antimatter via a box-diagram with Δms = 17.77 ± 0.10 (stat) ± 0.07 (syst) ps−1 measured by CDF experiment at Fermilab.

Surprisingly, the bizarre behavior of the B_s (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... CDF physicists have previously measured the rate of the matter-antimatter transitions for the B_s meson, which consists of the heavy bottom quark bound by the strong nuclear interaction to a strange antiquark.

[2]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".

[4] On 24 April 2013, CERN physicists in the LHCb collaboration announced that they had observed CP violation in the decay of strange B mesons for the first time.

[5][6] Scientists found the Bs meson decaying into two muons for the first time, with Large Hadron Collider experiments casting doubt on the scientific theory of supersymmetry.

[7][8] CERN physicist Tara Shears described the CP violation observations as "verification of the validity of the Standard Model of physics".
