Physics milestone: Key behavior of B-sub-s meson particle detemined

Fermilab has met the exacting standard to claim discovery of astonishingly rapid transitions between matter and antimatter: 3 trillion oscillations per second for the B-sub-s meson particle This is immediately significant for two major reasons: reinforcing the validity of the Standard Model, which governs physicists' understanding of the fundamental particles and forces; and narrowing down the possible forms of supersymmetry, a theory proposing that each known particle has its own more massive "super" partner particle.
