Tachyon condensation and Boundary States in Bosonic String
arXiv:hep-th/0001044 · doi:10.1142/9789812810380_0012
Abstract
We discuss tachyon configuration for the unoriented bosonic string theory which produces a bosonic string theory with SO(32) gauge symmetry in ten dimensions. It is closely related to the tachyon condensation scenario proposed by A. Sen. We also give the boundary state description of the tachyon condensation process, with some emphasis on the rôle of orbifold conformal field theory.
