Abstract
A closed-form expression is obtained for a holomorphic sector of the two-loop Euler-Heisenberg type effective action for N = 2 supersymmetric QED derived in hep-th/0308136. In the framework of the background-field method, this sector is singled out by computing the effective action for a background N = 2 vector multiplet satisfying a relaxed super self-duality condition. The approach advocated in this Letter can be applied, in particular, to the study of the N = 4 super-Yang-Mills theory on its Coulomb branch. (C) 2004 Elsevier B.V. All rights reserved.
