Wilson Lines and Classical Solutions in Cubic Open String Field Theory
نویسنده
چکیده
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 are well-defined in level truncation scheme, 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. ∗) E-mail: [email protected] ∗∗) E-mail: [email protected] 1 typeset using PTPTEX.sty §

Marginal and Scalar Solutions in Cubic Open String Field Theory
We find marginal and scalar solutions in cubic open string field theory by using left-right splitting properties of a delta function. The marginal solution represents a marginal deformation generated by a U(1) current, and it is a generalized solution of the Wilson lines one given by the present authors. The scalar solution has a well-defined universal Fock space expression, and it is expressed...
متن کاملMarginal Deformations and Closed String Couplings in Open String Field Theory
We investigate analytic classical solutions in open string field theory which are constructed in terms of marginal operators. In the classical background, we evaluate a coupling between an on-shell closed string state and the open string field. The resulting coupling exhibits periodic behavior as expected from the marginal boundary deformation of background Wilson lines or a marginal tachyon lu...
متن کاملDilaton Condensation in Cubic Open String Field Theory
We construct an exact and finite classical solution in cubic open string field theory. The classical solution has a well-defined Fock space expression. Through the redefinition of a string field, the string field theory expanded around the classical solution can be transformed into the theory with a different coupling constant, where other backgrounds are unchanged. Therefore, the classical sol...
متن کاملInteracting Open Wilson Lines from Noncommutative Field Theories 1
In noncommutative field theories, it was known that one-loop effective action describes propagation of non-interacting open Wilson lines, obeying the flying dipole’s relation. We show that two-loop effective action describes cubic interaction among ‘closed string’ states created by open Wilson line operators. Taking d-dimensional λ[Φ]⋆-theory as the simplest setup, we compute nonplanar contribu...
متن کاملExploring Vacuum Manifold of Open String Field Theory
The global symmetry generated by Kn is a subgroup of the stringy gauge symmetry. We explore the part of the vacuum manifold related by this symmetry. A strong evidence is presented that the analytic classical solutions to the cubic string field theory found earlier in Refs. [5, 6] are actually related by the symmetry and, therefore, all of them describe the same tachyon vacuum. Some remaining s...
