Erratum: Proton and neutron magnetic moments in quantum chromodynamics [JETP Lett. 37, No. 5, 298-301(5 March 1983)]
Ioffe B. L., Smilga A. V.
In the paper of B. L. IofFe and Α. V. Smilga, published in Vol. 37, No. 5, the following errors were missed. The signs in front of the terms proportional to χ and к on the left sides of Eqs. (3) and (4) should be changed to the opposite signs. The anomalous dimensionality of the quark current is attributable, as in Refs. 2 and 3 of this paper, to the incorrect sign. [One of the authors (B.I.) is indebted to Prof. G. Dosh for pointing out this error.] To correct this error the left sides of Eqs. (3) and (4) and the right sides of Eqs. (6) (those under the sign of differential operator) must be multiplied by L ~8/9. As a result, the value χ turns out to be χ = — 350 + 50 MeV-2, while the constants A and В become Ap = 3.4 GeV"2, An = 1.7 GeV~2, Bp =2.3 GeV-2, and Bn = — 3.7 GeV-2. Equations (7) for magnetic moments remain the same.
