Loop Corrected Tachyon Condensation

Abstract

We study loop corrections in boundary string field theory (BSFT). After commenting on problems with quantizing the tree level BSFT as an ordinary field theory, we discuss the tree level coupling to closed strings and define the loop corrections via factorization in the closed string channel. This description is weakly coupled in the vicinity of the closed string vacuum. Our proposal for the one-loop effective action differs in general from computing the annulus or cylinder partition functions. We also compute the decay rates and the loop corrections to the tensions of unstable branes in perturbative string theory.
