String Field Theory and the Fuzzy Sphere

Abstract

We use boundary string field theory to study open string tachyon condensation on a three-sphere closed string background. We consider the closed string background described by $SU(2{)}_k$ WZW model in the limit of large $k$. We compute the exact tachyon potential and analyse the decay modes.
