LHCb finds more matter-antimatter weirdness in B mesons
Matter and antimatter particles can behave differently, but where these differences show up is still a puzzle. Scientists on the LHCb experiment at the Large Hadron Collider study much more subtle differences between matter particles and their antimatter equivalents. A recent analysis allowed them to revisit an old mystery — an asymmetry between asymmetries.
LHCb observes rare decay
Standard Model predictions align with the LHCb experiment’s observation of an uncommon decay.
Discovery of rare decay narrows space for new physics
After a quarter of a century of searching, physicists have discovered a rare particle decay that gives them an indirect way to test models of new physics.
Fermilab scientists find evidence for significant matter-antimatter asymmetry
Scientists of the DZero collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced Friday, May 14, that they have found evidence for significant violation of matter-antimatter symmetry in the behavior of particles containing bottom quarks beyond what is expected in the current theory, the Standard Model of particle physics.
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.
Fermilab’s CDF scientists present a precision measurement of a subtle dance between matter and antimatter
Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced today (April 11, 2006) the precision measurement of extremely rapid transitions between matter and antimatter.
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.
