Abstract

New relations between the Borel sum rules in QCD for the magnetic moments of the Σ 0 and Λ hyperons are derived. It is shown that, on the basis of the sum rule for the magnetic moment of the Σ 0 hyperon, one can directly obtain the corresponding sum rule for the magnetic moment of the Λ hyperon, and vice versa, as well as the corresponding sum rule for the Σ 0 → Λ γ transition.
