Superfield approach to the construction of effective action in quantum field theory with extended supersymmetry
- Physics

We review the current state of research on the construction of effective actions in supersymmetric quantum field theory. Special attention is paid to gauge models with extended supersymmetry in the…
Construction of one-loop Script N = 4 SYM effective action in the harmonic superspace approach
- Mathematics
- 2005
We develop a systematic approach to construct the one-loop = 4 SYM effective action depending on both = 2 vector multiplet and hypermultiplet background fields. Beginning with the formulation of = 4…
Hypermultiplet dependence of one-loop effective action in the Script N = 2 superconformal theories
- Physics
- 2007
We study the one-loop low-energy effective action in the hypermultiplet sector for = 2 superconformal models. Any such a model contains an = 2 vector multiplet and some number of hypermultiplets.…

E(cid:11)ective actions in N = 1 , D5 supersymmetric gauge theories: harmonic superspace approach
- Physics

: We consider the o(cid:11)-shell formulation of the 5D, N = 1 super Yang-Mills and super Chern-Simons theories in harmonic superspace. Using such a formulation we develop a manifestly supersymmetric…

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 calculations. In this…
COMMENTS ON THE BACKGROUND FIELD METHOD IN HARMONIC SUPERSPACE: NON-HOLOMORPHIC CORRECTIONS IN N=4 SYM
- Mathematics
- 1998
We analyze the one-loop effective action of N=4 SYM theory in the framework of the bakground field formalism in N=2 harmonic superspace. For the case of onshell background N=2 vector multiplet we…
Harmonic supergraphs: Green functions
- Physics
- 1985
The quantisation procedure in the harmonic superspace approach is worked out. Harmonic distributions are introduced and are used to construct the analytic superspace delta functions and the Green…
Low-energy dynamics in N = 2 super QED: Two-loop approximation
- Physics
- 2003
The two-loop (Euler-Heisenberg-type) effective action for = 2 supersymmetric QED is computed using the = 1 superspace formulation. The effective action is expressed as a series in supersymmetric…
