Comments on regularization of identity based solutions in string field theory
arXiv:1009.0198 · doi:10.1007/JHEP11(2010)135
Abstract
We analyze the consistency of the recently proposed regularization of an identity based solution in open bosonic string field theory. We show that the equation of motion is satisfied when it is contracted with the regularized solution itself. Additionally, we propose a similar regularization of an identity based solution in the modified cubic superstring field theory.
