antimatter
From New Scientist, July 4, 2016: A new result from the NOvA and T2K experiments sheds light on the matter/antimatter imbalance in the early universe.
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.
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.
Scientists working at the Department of Energy’s Fermi National Accelerator Laboratory have announced a significant advance in the understanding of the difference in the way matter and antimatter behave.
