Wess-Zumino Term in Tachyon Effective Action

arXiv:hep-th/0304108 · doi:10.1088/1126-6708/2003/05/005

Abstract

We show that the source of RR field computed from the boundary state describing the decay of a non-BPS brane is reproduced by a particular form of the Wess-Zumino term in the tachyon effective action. We also obtain a simple expression of the S-charge associated with rolling tachyons.
