and electron, along with some additional theoretical assumptions.
At present the two methods do not agree very well, and in light of this disagreement some physicists only use the direct method to determine the theory value. The data used in both methods were obtained at accelerators in Russia, Europe, China, and the U.S. Data from additional experiments at accelerators in the U.S., Italy, and Japan, when available, should help to further refine the Standard Model theory value for g-2, giving scientists greater confidence in the number used for comparison with the experimental result announced today.
This research was funded by the Office of High Energy Physics within the Office of Science of the U.S. Department of Energy, the U.S. National Science Foundation, the German Bundesminister fur Bildung und Forschung, and the Russian Ministry of Science, and through the U.S.-Japan Agreement in High Energy Physics.
