چکیده
We investigate the perturbative part of Seiberg’s low-energy effective action of N = 2 supersymmetric Yang-Mills theory in Wess-Zumino gauge in the conventional effective field theory technique. Using the method of constant field approximation and restricting the effective action with at most two derivatives and not more than four-fermion couplings, we show some features of the low-energy effective action given by Seiberg based on U(1)R anomaly and non-perturbative β-function arguments.

We consider N = 4 supersymmetric Yang-Mills theory formulated in terms of N = 2 superfields in harmonic superspace. Using the background field method we define manifestly gauge invariant and N = 2 supersymmetric effective action depending on N = 2 strength superfields and develop a general procedure for its calculation in one-loop approximation. Explicit form for this effective action is found ...

We consider the theories obtained by dimensional reduction to D = 1, 2, 3 of 4D supersymmetric Yang–Mills theories and calculate there the effective low-energy lagrangia describing moduli space dynamics — the low-dimensional analogs of the Seiberg–Witten effective lagrangian. The effective theories thus obtained are rather beautiful and interesting from mathematical viewpoint. In addition, thei...

In contrast with the classical gauge group cases, any method to prove exactly the scaling relation which relates moduli and prepotential is not known in the case of exceptional gauge groups. This paper provides a direct method to establish this relation by using Picard-Fuchs equations. In particular, it is shown that the scaling relation found by Ito in N = 2 supersymmetric G 2 Yang-Mills theor...

We study N = 2 supersymmetric Born-Infeld-Higgs theory in 3 dimensions and derive Bogomol’nyi relations in its bosonic sector. A peculiar coupling between the Higgs and the gauge field (with dynamics determined by the Born-Infeld action) is forced by supersymmetry. The resulting equations coincide with those arising in the MaxwellHiggs model. Concerning Bogomol’nyi bounds for the vortex energy,...
