# Comments on Gauge Invariant Overlaps for Marginal Solutions in Open String Field Theory

@article{Kishimoto2008CommentsOG, title={Comments on Gauge Invariant Overlaps for Marginal Solutions in Open String Field Theory}, author={Isao Kishimoto}, journal={Progress of Theoretical Physics}, year={2008}, volume={120}, pages={875-886} }

We calculate the gauge invariant overlaps for Schnabl/Kiermaier-Okawa-RastelliZwiebach’s marginal solution with nonsingular current. The obtained formula is the same as that for Fuchs-Kroyter-Potting/Kiermaier-Okawa’s marginal solution, which was already computed by Ellwood. Our result is consistent with the expectation that these two solutions may be gauge equivalent. We also comment on a gauge invariant overlap for rolling tachyon solutions in cubic open string field theory.
