Propagators on One-Loop Worldsheets for Orientifolds and Intersecting Branes
F. Epple
We obtain the one-loop propagators in superstring theory for the general case when the worldsheet fields satisfy non-trivial holonomy and/or boundary conditions. Non-trivial holono…

Induced Gravity on Intersecting Branes
Friedel Epple
We establish Einstein-Hilbert gravity couplings in the effective action for Intersecting Brane Worlds. The four-dimensional induced Planck mass is determined by calculating gravito…

Tachyon Condensation for Intersecting Branes at Small and Large Angles
F. Epple, D. Lust
We review the worldsheet analysis for intersecting branes with focus on small and large angles. For small angles, we review the Yang-Mills fluctuation analysis in hep-th/0303204 an…
