String field theory and the fuzzy sphere

Harald Ita, Yaron Oz

Research output: Contribution to journalArticlepeer-review


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.
