Toy Model for Tachyon Condensation in Bosonic String Field Theory

Pieter-Jan De Smet, Joris Raeymaekers, Celestijnenlaan D, B- Leuven

Abstract

We study tachyon condensation in a baby version of Witten's open string field theory. For some special values of one of the parameters of the model, we are able to obtain closed form expressions for the stable vacuum state and for the value of the potential at the minimum. We study the convergence rate of the level truncation method and compare our exact results with the numerical results found in the full string field theory.
