Structure of Low-Energy Effective Action in N=4 Supersymmetric Yang-Mills Theories
نویسنده
چکیده
We study a problem of low-energy effective action in N=4 super Yang-Mills theories. Using harmonic superspace approach we consider N=4 SYM in terms of unconstrained N=2 superfield and apply N=2 background field method to finding effective action for N=4 SU(n) SYM broken down to U(n)n−1. General structure of leading low-energy corrections to effective action is discussed and calculational procedure for their explicit finding is presented.

Duality in N = 2 , 4 supersymmetric gauge theories ∗
In these lectures we present a detailed description of various aspects of gauge theories with extended N = 2 and N = 4 supersymmetry that are at the basis of recently found exact results. These results include the exact calculation of the low energy effective action for the light degrees of freedom in the N = 2 super Yang-Mills theory and the conjecture, supported by some checks, that the N = 4...

We investigate the low-energy effective action in N=4 super Yang-Mills theory with gauge group SU (n) spontaneously broken down to its maximal torus. Using harmonic superspace technique we prove an absence of any three-and four-loop corrections to non-holomorphic effective potential depending on N = 2 superfield strengths. A mechanism responsible for vanishing arbitrary loop corrections to low-...

We study the perturbation expansion of the free energy of N = 4 supersymmetric SU(N) Yang-Mills at finite temperature in powers of ’t Hooft’s coupling g2N in the large N limit. Infrared divergences are controlled by constructing a hierarchy of two 3 dimensional effective field theories. This procedure is applied to the calculation of the free energy to order (g2N)3/2, but it can be extended to ...
