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) The non perturbative story of brane supersymmetry breaking vacua Carlo Angelantonj will lead a discussion on: "The non perturbative story of brane supersymmetry breaking vacua" Abstract: We argue that tachyon-free type I string vacua with supersymmetry breaking in the open sector at the string scale can be interpreted, via S and T-duality arguments, as metastable vacua of supersymmetric type I superstring. The dynamics of the process can be partially captured via nucleation of brane-antibrane pairs out of the non-supersymmetric vacuum and subsequent tachyon condensation.
