Surprisingly, the bizarre behavior of the B0s (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 B0s meson, which consists of the heavy bottom quark bound by the strong nuclear interaction to a strange antiquark.
For CDF's result the probability is even smaller, at 8 in 100 million (8/100000000 = 1/12500000).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".
[6] However, more recent results at LHCb with larger data samples have suggested no significant deviation from the Standard Model.
[9] On 21 February 2017, the LHCb collaboration announced that the rare decay of a neutral B meson into two oppositely charged kaons had been observed to a statistical significance of 5σ.
