This book presents the supereld description of various supersymmetric eld theory models in three- and four-dimensional space-times. A mapping between supereld and component formulations of supersymmetric eld theories is discussed. The author also describes the methodology for calculating quantum corrections in these theories employing supergraph formalism and functional methods, and illustrates these approaches with many detailed examples of how such calculations are performed for various supereld models.

Includes many explicit detailed super?eld quantum calculations presented for the first time in a book. Presents well-known theories alongside novel information on supersymmetric ?eld theory models Concentrates on perturbative aspects of super?eld theory models

Klappentext

This book presents the super eld description of various supersymmetric eld theory models in three- and four-dimensional space-times. A mapping between super eld and component formulations of supersymmetric eld theories is discussed. The author also describes the methodology for calculating quantum corrections in these theories employing supergraph formalism and functional methods, and illustrates these approaches with many detailed examples of how such calculations are performed for various super eld models.

Zusammenfassung
"The exposition is comprehensive and the calculations are explicit at each step, thus making the book pedagogical and valuable also for the non-expert reader. Many explicit examples are worked out in detail, both in three and in four dimensions." (Niccolò Cribiori, Mathematical Reviews, September, 2022)
