Analytic solutions for marginal deformations in open superstring field theory
arXiv:0704.0936 · doi:10.1088/1126-6708/2007/09/084
Abstract
We extend the calculable analytic approach to marginal deformations recently developed in open bosonic string field theory to open superstring field theory formulated by Berkovits. We construct analytic solutions to all orders in the deformation parameter when operator products made of the marginal operator and the associated superconformal primary field are regular.
