Subject(s): DDC classification:
  • 539.758 23 El51
Contents:
1. Introduction -- Part I. Trees: 2. Spinor helicity formalism -- 3. On-shell recursion relations at tree-level -- 4. Supersymmetry -- 5. Symmetries of N = 4 SYM -- Part II. Loops: 6. Loop amplitudes and generalized unitarity -- 7. BCFW reclusion for loops -- 8. Leading singularities and on-shell diagrams -- Part III. Topics: 9. Grassmannia -- 10. Polytopes -- 11. Amplitudes in dimensions -- 12. Supergravity amplitudes -- 13. A colorful duality -- 14. Further reading.
Summary: This book is ideal for graduate students and researchers. It offers a smooth transition from basic knowledge of quantum field theory to the frontier of modern research. Building on basic quantum field theory, the book starts with an introduction to the spinor helicity formalism in the context of Feynman rules for tree-level amplitudes. The material covered includes on-shell recursion relations, superamplitudes, symmetries of N=4 super Yang-Mills theory, twistors and momentum twistors, Grassmannians, and polytopes. The presentation also covers amplitudes in perturbative supergravity, 3D Chern-Simons matter theories, and color-kinematics duality and its connection to 'gravity=(gauge theory)2'. Basic knowledge of Feynman rules in scalar field theory and quantum electrodynamics is assumed, but all other tools are introduced as needed. Worked examples demonstrate the techniques discussed, and over 150 exercises help readers absorb and master the material.This book grew out of a need to have a set of easily accessible notes that introduced the basic techniques used in modern research on scattering amplitudes.
