On the structure of exact effective action for N=1 supersymmetric theories
K. Stepanyantz
We discuss the ways of constructing the exact superpotential for N=1 supersymmetric theories and propose a new approach. As a consequence, a new structure of the superpotential is…
Exact effective action for N=1 supersymmetric theories
P. Pronin, K. Stepanyantz
We investigate nonperturbative effects in N=1 supersymmetric theories and propose a new expression for the effective action, which correctly reproduces quantum anomalies and agrees…
Anomalies and nonperturbative results
P. Pronin, K. Stepanyantz
We investigate nonperturbative effects in N=1 and N=2 supersymmetric theories using a relation between perturbative and exact anomalies as a starting point. For N=2 supersymmetric…
On the value of coupling constant
P. Pronin, K. Stepanyantz
Using an analogy between Bogomol'nyi bound and the harmonic oscillator in quantum mechanics we propose a possible explanation of the coupling constant numerical value at the grand…
