The muon (g-2) experiment at Brookhaven National Laboratory was initiated in 1984 by Sterling Professor Emeritus Vernon W. Hughes from Yale, and is presently run by an international collaboration of more than 60 physicists from 13 institutes in the United States, Germany, Russia and Japan. A press release from Brookhaven quotes Professor Hughes: “Our new, higher-precision measurement of muon (g-2) provides a unique and unusually sensitive test of the validity of the general theory of electromagnetism or, equivalently of the Standard Model of particle physics. The present difference between our experimental result and theoretical predictions may indicate new physics beyond the Standard Model. Effects on (g-2) of speculative new theories have been extensively discussed in the literature.” Technical information is available on this web site at Yale, including the original research paper.
