SUSY implies that these correlation functions do not depend on coordinates and vanish identically in perturbation theory. A technique is developed for the systematic calculation of instanton effects. It is shown that even in the limit x -> 0 the correlation functions at hand are not saturated by small-size instantons with radius rho approximately x; a contribution of the same order of magnitude comes from the instantons of characteristic size pro approximately 1/V (V is the vacuum expectation value of the scalar field, and the attention is paid to the models with V >> lambda where lambda is the scale parameter fixing the running gauge coupling constant). If V > lambda both types of instantons can be consistently taken into account. The computational formalism proposed is explicitly supersymmetric and uses the language of instanton-associated superfields. (Atomindex citation 17:020151) 收起
