Özet

New relations between the Borel QCD sum rules for the strong couplings of the ∑0 and Λ hyperons are derived. It is shown that, using the sum rules for g M∑∑, M = π 0, η, as a starting point, one can readily obtain the corresponding sum rules for the coupling constants g ηΛΛ and g πΛ∑ 0. The values of these constants are calculated in a specific parameter region. © Pleiades Publishing, Inc., 2006.
