Type I superstring and heterotic string

Shiying Dong (UIUC Physics)

Abstract: We'll discuss gauge symmetry in the context of the open string, and then find that the only consistent unoriented superstring theory is with gauge group SO(32). This theory has N=1 spacetime supersymmetry. Then we restrict the worldsheet superconformal symmetry to the right moving side, and find the heterotic string.
