The schedule for this Journal Club on String Theory will be as follows: 1) The latest news in the world of strings Please bring papers that caught your recent attention and briefly summarize motivations, methods and results. 2) Non-perturbative corrections in IIB orientifolds Gabriele Honecker will lead a discussion on: "Non-perturbative corrections in IIB orientifolds" Abstract: Non-perturbative corrections to the Kaehler potential in N=1 IIB orientifold compactifications arise from both b-field moduli and D-instantons. Following 0705.2353 I am discussing these effects and how they constrain the non-perturbative superpotential. Compactification on the Enriques Calabi-Yau serves as a simple example.
