Introduction

Petrov, Albert

Pages: 1 –3

[The idea of supersymmetry is now considered as one of the basic concepts of theoretical high energy physics (see e.g. [1]). The supersymmetry, being a fundamental symmetry allowing to relate bosons and fermions, provides possibilities to construct theories with much better renormalization...

Effective Action and Loop Expansion: General Formulation

Petrov, Albert

Pages: 5 –9

[In this chapter we present the description of its general structure and manners of its calculation, which in the next chapters will be applied to supersymmetric field theories.]

Superfield Description of Three-Dimensional Supersymmetric Theories

Petrov, Albert

Pages: 11 –47

[In this chapter we describe the superfield formalism for three-dimensional supersymmetric field theory models. Afterwards, we describe various approaches to calculate quantum corrections in three-dimensional superfield theories, including the noncommutative ones. These approaches are illustrated...

Four-Dimensional Superfield Supersymmetry

Petrov, Albert

Pages: 49 –141

[Basing on our experience with studies of three-dimensional supersymmetric field theory models, now we turn to our main aim—study of a superfield description for four-dimensional supersymmetric field theories. We discuss their superfield formulations and manners to calculate quantum corrections...

Supersymmetry Breaking

Petrov, Albert

Pages: 143 –146

[Throughout these lecture notes, we have discussed the superfield methodology for studying supersymmetric field theories. However, it is known that, actually the supersymmetry is broken at observed scales of energy. There are two ways to describe the breaking of any symmetry including the...

Conclusions

Petrov, Albert

Pages: 147 –149

[In this book, we considered the superfield method in supersymmetric field theories, both in three- and four-dimensional space-times. This method allows to preserve the manifest supersymmetry at any step of calculations, and the calculations within it turn out to be much more compact than within...
