I will introduce into the subject of string amplitudes and present many
recent advances on tree-level open and closed superstring amplitudes
including BCJ and KLT structure, motivic and single-valued multiple zeta values.
|
| |
The plan of the course is:
|
|
| |
0. Motivation for string scattering amplitudes.
1. String amplitudes: world-sheet geometry and conformal field theory.
2. General properties from string world-sheet.
3. General structure of open superstring amplitudes.
4. Closed string amplitudes.
5. Mixed amplitudes involving both open and closed strings.
6. Motivic superstring amplitudes.
