QCD Sum Rules: Intercrossed Relations for the Sigma^0-Lambda Mass Splitting

Abstract

New relations between QCD Borel sum rules for masses of Sigma^0 and Lambda hyperons are constructed. It is shown that starting from the sum rule for the Sigma^0 hyperon mass it is straightforward to obtain the corresponding sum rule for the Lambda hyperon mass and vice versa.
