摘要：

We report the result of our calculation of the complete tenth-order QED terms of the muon g - 2. Our result is a(mu)((10)) = 753.29 (1.04) in units of (alpha/pi)(5), which is about 4.5 s.d. larger than the leading-logarithmic estimate 663(20). We also improve the precision of the eighth-order QED term of a(mu), obtaining a(mu)((8)) = 130.8794 (63) in units of (alpha/pi)(4). The new QED contribution is a(mu) (QED) = 116 584 718 951 (80) X 10(-14), which does not resolve the existing discrepancy between the standardmodel prediction and measurement of a(mu).
