Superstring perturbation theory - Ashoke Sen (Lecture 3)
Part of LonTI lectures Spring 2025.
Title: Superstring perturbation theory
Lecturer: Prof. Ashoke Sen (ICTS, Bangalore)
Date: 2 June 2025
Place: King's College London
Topics to be discussed:
The world-sheet CFT for bosonic string theory, matter and ghost system, BRST charge, physical state condition
Definition of higher genus Riemann surfaces, defining CFT correlations on higher genus Riemann surfaces, bosonic string amplitudes at any loop order
Heterotic and superstring theory, world-sheet CFT of matter and ghosts, picture number and picture changing operator, superstring amplitude at any loop order
Vertical integration and removal of spurious divergences
