Title:
On the Relationship Between Super-Riemann Surfaces and PCOs
Speaker:
Abstract:
We will discuss the relationship between the two formulations of superstring perturbation theory: the SRS formalism, based on integration over the supermoduli space of super-Riemann Surfaces, and the PCO formalism, based on integration over bosonic moduli space with insertions of picture changing operators and vertical integration. I will show that the picture changing operator approach arises from a specific construction of the supermoduli integration contour. If time permits, I will also discuss an explicit construction in genus two.
