Description
The chiral properties of low-energy matrix elements of four-quark operators describing the weak vertices in the effective Lagrangian of weak interactions are investigated. A constituent quark diagram technique for the derivation of ''soft'' pion low-energy theorems is proposed. The technique is applied to the calculation of the Σ-term operator correlator in the low-energy theorem of the penguin-operator matrix elements. (author) 19 refs
