Supersymmetry and String Theory

Click For Summary
SUMMARY

The discussion centers on the concepts presented in Michael Hines' book, "Supersymmetry and String Theory," specifically the term "tree-level." Tree-level refers to Feynman diagrams that do not contain loops, representing the 0th order in perturbation theory, which is crucial for understanding quantum field theory. This foundational concept is essential for grasping the complexities of supersymmetry and string theory.

PREREQUISITES
  • Understanding of Feynman diagrams
  • Basic knowledge of perturbation theory
  • Familiarity with quantum field theory
  • Concept of supersymmetry
NEXT STEPS
  • Research the role of Feynman diagrams in quantum mechanics
  • Study perturbation theory in detail
  • Explore the implications of tree-level calculations in string theory
  • Investigate advanced concepts in supersymmetry
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in advanced topics in quantum mechanics and string theory.

I am reading Michael Hines new book, Supersymmetry and String Theory. He keeps referring to "tree-level". What is this?

"Tree-level" refers to Feynman diagrams with no loops. That is, 0th order in perturbation theory (h-bar).
