Non-holomorphic effective potential in N = 4 SU(n) SYM
E. I. Buchbinder, I. L. Buchbinder, S. M. Kuzenko
We compute the one-loop non-holomorphic effective potential for the N=4 SU(n) supersymmetric Yang-Mills theory with the gauge symmetry broken down to the maximal torus. Our approac…
Covariant Harmonic Supergraphity for N = 2 Super Yang--Mills Theories
Ioseph Buchbinder, Sergei Kuzenko, Burt Ovrut
We review the background field method for general N = 2 super Yang-Mills theories formulated in the N = 2 harmonic superspace. The covariant harmonic supergraph technique is then a…
Comments on the Background Field Method in Harmonic Superspace: Non-holomorphic Corrections in N=4 SYM
I. L. Buchbinder, S. M. Kuzenko
We analyse the one-loop effective action of N=4 SYM theory in the framework of the background field formalism in N=2 harmonic superspace. For the case of on-shell background N=2 ve…
Central Charge as the Origin of Holomorphic Effective Action in N=2 Gauge Theory
E. I. Buchbinder, I. L. Buchbinder, E. A. Ivanov +1
We explicitly demonstrate that the perturbative holomorphic contribution to the off-shell effective action of N=2 U(1) gauge supermultiplet is an entire effect of the minimal coupl…
Background Field Method and Structure of Effective Action in N=2 Super Yang-Mills Theories
I. L. Buchbinder, B. A. Ovrut
This paper is a brief review of background field method and some of its applications in N=2 super Yang-Mills theories with a matter within harmonic superspace approach. A general s…
Effective Action of N=2 Supersymmetric Field Theories in Harmonic Superspace Approach
I. L. Buchbinder
The paper is a brief review of the works devoted to problem of effective action in N=2 super Yang-Mills theories in harmonic superspace approach. The formulation of N=2 superfield…
