a greater matter-antimatter disparity than that predicted by the Standard Model of the universe was reported on May 14 by the DZero collaboration at Fermi National Accelerator Laboratory. Assessing experimental results from the past eight years, with the polarity of the detector's magnetic field reversed during data collection to rule out instrumental effects, the researchers found a I percent difference between the production of pairs of muons and pairs of arttimuons in the decay of B mesons created in collisions at FermiLab's Tevatron accelerator. This is far greater than the previously observed prevalence of matter over antimatter but may be a better depiction of the disparity that actually exists in the universe. The results were submitted for publication in the journal Physical Review D.
