Exact Solutions in Open Bosonic String Field Theory and Marginal Deformation in CFT
arXiv:hep-th/0209255 · doi:10.1142/S0217751X04019329
Abstract
In this paper we continue our study f the exact solution in open bosonic string field theory. We present new solution in the string field theory defined on the background corresponding to the boundary conformal field theory describing D25-brane. Then we will study the fluctuation modes around this solution and we determine their basic properties from the linearised equation of motion of the string field theory defined above the classical solution.
