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) "Kaluza-Klein relics from warped reheating", discussion led by James Cline Abstract: After brane-antibrane inflation in a Klebanov-Strassler throat, closed string modes including KK gravitons are produced by the brane-antibrane annihilation. Due to isometries of the throat's angular directions, some of these KK modes would be stable, creating a problem of heavy relics. Gluing the throat to the bulk Calabi-Yau weakly breaks the isometries and allows the KK relics to decay, leading to constraints on the warp factor in the throat, and on the scale of SUSY breaking. Hope to see you all!! Gabriele Honecker Fernando Marchesano Nikolaos Prezas Ricardo Schiappa References: arXiv:0710.1299 [hep-th]
