Fermilab’s CDF scientists make it official: They have discovered the quick-change behavior of the B-sub-s meson, which switches between matter and antimatter 3 trillion times a second

Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced today (September 25, 2006) that they have met the exacting standard to claim discovery of astonishingly rapid transitions between matter and antimatter: 3 trillion oscillations per second.

What Happened to the Antimatter? Fermilab’s DZero Experiment Finds Clues in Quick-Change Meson

Scientists of the DZero collider detector collaboration at the Department of Energy’s Fermi National Accelerator Laboratory have announced that their data on the properties of a subatomic particle, the B_s meson (“B sub s”), suggest that the particle oscillates between matter and antimatter in one of nature’s fastest rapid-fire processes-more than 17 trillion times per second.
