New bi-harmonic superspace formulation of SYM theory
arXiv:2012.09669 · doi:10.1007/JHEP04(2021)010
Abstract
We develop a novel bi-harmonic superspace formulation of the supersymmetric Yang-Mills theory (SYM) in four dimensions. In this approach, the SYM superfield constraints are solved in terms of on-shell harmonic superfields. Such an approach provides a convenient tool of constructing the manifestly supersymmetric invariants and further rewriting them in harmonic superspace. In particular, we present superfield form of the leading term in the SYM effective action which was known previously in superspace formulation.
