Constrained superpotentials in harmonic gauge theories with 8 supercharges

Abstract

We consider D-dimensional supersymmetric gauge theories with 8 supercharges (D<6,$\mathcal{N}=8$) in the framework of harmonic superspaces. The effective Abelian low-energy action for D=5 contains the free and Chern-Simons terms. Effective $\mathcal{N}=8$ superfield actions for D<4 can be written in terms of the superpotentials satisfying the superfield constraints and (6-D)-dimensional Laplace equations. The role of alternative harmonic structures is discussed.
