Abstract
New relations between QCD Borel sum rules for masses of Σ0 and Λ hyperons are constructed. It is shown that starting from the sum rule for the Σ0 hyperon mass it is straightforward to obtain the corresponding sum rule for the Λ hyperon mass and vice versa. © World Scientific Publishing Company.
