Effective actions in =1, D5 supersymmetric gauge theories: harmonic superspace approach

arXiv:1510.02563 · doi:10.1007/JHEP11(2015)130

Abstract

We consider the off-shell formulation of the 5D, =1 super Yang-Mills and super Chern-Simons theories in harmonic superspace. Using such a formulation we develop a manifestly supersymmetric and gauge invariant approach to constructing the one-loop effective action both in super Yang-Mills and super Chern-Simons models. On the base of this approach we compute the leading low-energy quantum contribution to the effective action on the Abelian vector multiplet background. This contribution corresponds to invariant which is given in 5D superfield form.
