String Theory 2: Fermionic Strings - Lecture 9

Explore the fundamentals of fermionic strings in this 90-minute lecture from the PHY453.5 String Theory course at the International Centre for Theoretical Sciences. Professor Ashoke Sen delves into advanced topics including Free Heterotic String, Free Type II and Type I Superstring theories, interactions, picture changing operators, and amplitude computations. This lecture, part of a series scheduled on Tuesdays and Thursdays starting January 21, 2025, builds upon prerequisites in Quantum Field Theory, General Relativity, and introductory String Theory. Gain valuable knowledge in computing the spectrum and interactions in supersymmetric string theories through this comprehensive theoretical physics presentation.
