Abstract

Using formulation of \cal N=4 SYM theory in terms of \cal N=1 superfields superfields we construct the derivative expansion of the one-loop \cal N=4 SYM effective action in background fields corresponding to constant Abelian strength F_mn and constant hypermultiplet. Any term of the effective action derivative expansion can be rewritten in terms of \cal N=2 superfields. The action is manifestly \cal N=2 supersymmetric but on-shell hidden \cal N=2 supersymmetry is violated. We propose a procedure which allows to restore the hidden \cal N=2 invariance.
