Low-energy dynamics in N = 2 super QED: Two-loop approximation
S. M. Kuzenko, I. N. McArthur
The two-loop (Euler-Heisenberg-type) effective action for N = 2 supersymmetric QED is computed using the N = 1 superspace formulation. The effective action is expressed as a series…

On the Background Field Method Beyond One Loop: A manifestly covariant derivative expansion in super Yang-Mills theories
S. M. Kuzenko, I. N. McArthur
There are currently many string inspired conjectures about the structure of the low-energy effective action for super Yang-Mills theories which require explicit multi-loop calculat…
