Abstract
We construct an analytic solution for tachyon condensation around identitybased marginal solutions in Berkovits’ WZWlike open superstring field theory Using this which is a kind of wedgebased solution the gauge invariant overlaps for the identitybased marginal solutions can be calculated analytically This is a straightforward extension of a method in bosonic string field theory which has been elaborated by the authors to superstring We also comment on a gauge equivalence relation between the tachyon vacuum solution and its marginally deformed one From this viewpoint we can find the vacuum energy of the identitybased marginal solutions to be zero which agrees with the previous result as a consequence of ξ zero mode countingThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
