Pravilo summ vyektornykh tokov i narushyennyi{cyrillic, short} magnitnyi{cyrillic, short} momyent Σ⁺(*)

A familiar vector-current sum rule of the Fubini-Furlan-Rossetti type is presented, and a model for the continuum corrections evolved. The symmetry breaking is introduced in a simple way by coupling the spurion in the sum rule to the baryon line in the graphs which contribute to the continuum terms. The decuplet does not contribute in this low-energy model. The correction terms turn out to be typically a few tenths of a magneton. The result for the Σ⁺ moment, which depends on the D/F ratio, is, for the usual choice of this ratio, Σ⁺ nuclear magnetons.
