Tachyon Condensation for Intersecting Branes at Small and Large Angles

Abstract

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 and find an additional family of massless modes. They are the components of a Goldstone scalar corresponding to the spontaneously broken U(2)-gauge symmetry. For branes at large angles, we derive an effective tachyon field theory from BSFT results. We show how the gauge symmetry of this system implies a mass spectrum which is consistent with the worldsheet analysis.
