Quantum calculation of the low-energy effective action in 5D, N=2 SYM theory

Abstract

We consider 5D, N = 2 supersymmetric Yang-Mills (SYM) theory in 5D, N = 1 harmonic superspace as a theory of the interacting adjoint 5D, N = 1 gauge multiplet and hypermultiplet. Using the background superfield method, we compute the leading low-energy contribution to the one-loop effective action. The result of quantum calculations precisely matches the effective action derived earlier in arXiv:1812.07206 on the pure symmetry grounds.
