Analytic Solutions for Marginal Deformations in Open String Field Theory
We develop a calculable analytic approach to marginal deformations in open string field theory using wedge states with operator insertions. For marginal operators with regular operator products, we construct analytic solutions to all orders in the deformation parameter. In particular, we construct an exact time-dependent solution that describes D-brane decay and incorporates all α′ corrections....
متن کاملLarge Marginal Deformations in String Field Theory
We use the level truncation scheme to obtain accurate descriptions of open bosonic string field configurations corresponding to large marginal deformations such as background Wilson lines. To do so, we solve for all fields as functions of the massless string field, and confirm that the effective potential of the massless field becomes increasingly flat as the level of approximation is increased...
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 کاملMarginal Deformations as Lower Dimensional D–brane Solutions in Open String Field theory
By direct calculation we showed that a finite analytic solution for marginal deformation of open string field theory, by a matter primary operator with singular OPE, can be obtained to all orders in the deformation parameter. In particular, we obtained solutions that describe lower dimensional D–branes and our results agree with the results obtained when the same problem is treated in the world...
متن کاملMarginal Deformations In the Open Bosonic String Field Theory for N D0-branes
In this short note we give an example of the exact solution of the open bosonic string field theory defined on the background of N coincided D0-branes. This solution leads to the change of the original background to the background where D0-branes are localised in general positions.
