Bv. Geshkenbein et Vl. Morgunov, ON THE HADRONIC CONTRIBUTION TO THE MUON (G-2)-FACTOR AND TO THE ALPHA(M(Z)(2)), Physics letters. Section B, 352(3-4), 1995, pp. 456-460
The hadronic vacuum-polarization contributions to the muon anomalous m
agnetic momentum a(mu)(hadr.) and to the value of the electromagnetic
coupling constant at q(2) = M(z)(2) are calculated with the record acc
uracy. A QCD model with an infinite number of vector mesons suggested
by one of the authors is used. In this model the non-perturbative effe
cts are included automatically. The results are: a(mu)(hadr.) = 670(7)
x 10(-10), a(mu)(theor.) = 11659153(7) x 10(-10), delta alpha(hadr),
(M(z)(2)) = 0.02780(6)and alpha(M(z)(2)) = (128.921(8))(-1).
