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. 

Numerical evaluation of gauge invariants for a-gauge solutions in open string field theory

We evaluate gauge invariants (the action and the gauge-invariant overlap) for numerical solutions satisfying the “a-gauge” condition with various values of a in the cubic open bosonic string field
