摘要：
The magnetic moment mu of the rho meson is calculated in the framework of QCD sum rules in external fields. Bare-loop calculations (parton model) give mu(part) = 2.0 (in units e/(2mrho)). The contribution of operators of dimension 6 reduces this value: mu = 1.5 +/- 0.3. (C) 2005 Pleiades Publishing, Inc.
