Comments on Marginal Deformations in Open String Field Theory
arXiv:hep-th/0701248 · doi:10.1016/j.physletb.2007.08.023
Abstract
In this short letter we present a class of remarkably simple solutions to Witten's open string field theory that describe marginal deformations of the underlying boundary conformal field theory. The solutions we consider correspond to dimension-one matter primary operators that have non-singular operator products with themselves. We briefly discuss application to rolling tachyons.
