Particle Oscillates Between Matter and Anti-Matter

Scientists at Fermilab have announced they've "met the exacting standard to claim discovery of astonishingly rapid transitions between matter and antimatter: 3 trillion oscillations per second." The measurements were made of the B-sub-s meson -- mesons are non-elementary particles that are theorized to be composed a quark-antiquark pair -- in the B-sub-s meson's case, it is a heavy bottom quark and a strange antiquark. The finding reaffirms the validity of the Standard Model of physics by observing the oscillatory behaviour predicted and narrows the possible forms of supersymmetry.
