Bi-harmonic superspace for d = 4 super Yang-Mills

We develop d  = 4 bi-harmonic superspace and use it to derive a novel form for the low-energy effective action in super Yang-Mills theory. We solve the supergauge constraints in this superspace in terms of analytic superfields. Using these superfields, we construct a simple functional that respects...

Zusammenfassung:We develop d  = 4 bi-harmonic superspace and use it to derive a novel form for the low-energy effective action in super Yang-Mills theory. We solve the supergauge constraints in this superspace in terms of analytic superfields. Using these superfields, we construct a simple functional that respects supersymmetry and scale invariance. In components, it reproduces all on-shell terms in the four-derivative part of the SYM effective action; in particular, the F 4 / X 4 and Wess-Zumino terms. The latter comes out in a novel SO(3) × SO(3)-invariant form.
