Aims
Understanding the apparent complexity and hidden simplicity of scattering amplitudes in gauge theories and perturbative gravity

Identifying aspects of gravity as a double copy of gauge theories
Requirements
Einführung in die Quantenfeldtheorie
Einführung in die Elementarteilchenphysik
Structure / topics / contents
1) Non-abelian gauge theories, perturbative gravity and their Feynman rules

2) Spinor-helicity variables

3) Tree-level amplitudes in gauge theories I: color decomposition, Parke—Taylor formula, Berends—Giele recursion

4) Tree-level amplitudes in gauge theories II: Duality between color & kinematics and Bern—Carrasco—Johansson amplitude relations

5) Double-copy construction of gravitational tree amplitudes & Kawai—Lewellen—Tye amplitude relations

6) Aspects of supersymmetry and color-kinematics duality & double copy in loop amplitudes

7) Double-copy relations between classical solutions of gauge theories and gravity
