摘要:
The Muong‐ 2 collaboration has measured the anomalous magneticgvalue,a= (g‐ 2)/2, of the positive muon with an unprecedented uncertainty of 0.7 parts per million. The resulta&mgr;+(expt) = 11659204(7)(5) × 10−10, based on data collected in the year 2000 at Brookhaven National Laboratory, is in good agreement with the preceeding data ona&mgr;+anda&mgr;−. The measurement tests standard model theory, which at the level of the current experimental uncertainty involves quantum electrodynamics, quantum chromodynamics, and electroweak interaction in a significant way. © 2003 American Institute of Physics
