Wilson Lines and Classical Solutions in Cubic Open String Field Theory

Abstract

We construct exact classical solutions in cubic open string field theory. By the redefinition of the string field, we find that the solutions correspond to finite deformations of the Wilson lines. The solutions have well-defined Fock space expressions, and they have no branch cut singularity of marginal parameters which was found in the analysis using level truncation approximation in Feynman-Siegel gauge. We also discuss marginal tachyon lump solutions at critical radius.Comment: 12 pages, LaTeX with PTPTeX.sty; minor corrections, comments adde

Marginal deformations in the open bosonic string field theory for N D0 branes

“…We have shown that there exist exact solution of the open bosonic string field theory that describes any marginal deformation of the original configuration of N D0-branes localized in the origin of the space to the background configuration of N D0-branes in general positions. We have also seen that using the regulation of the solution, following [5,6,7] we have obtained solutions that is completely non singular. This fact can be used as an explanation of the presence of the singular term in the exact solution given in our previous work [14].…”

“…However it is a pleasant duty for us mention some of the papers [5,6,7,8,9] that discuss related problems from different point of view.…”

Solving Witten's SFT by Insertion of Operators on Projectors

“…Since we will insert the operators on the middle point of the boundary, the following η = I(z) = − 1 z representation is useful: 9) which maps the middle point of the boundary to η = 0, as illustrated in figure (1). The star product of two projectors can be easily done inẑ representation.…”
