Closed String Amplitudes in Open String Field Theory
Tomohiko Takahashi, Syoji Zeze
We investigate gauge invariant operators corresponding to on-shell closed string states in open string field theory. Using both oscillator representation and conformal mapping tech…

Gauge Fixing and Scattering Amplitudes in String Field Theory Expanded around Universal Solutions
Tomohiko Takahashi, Syoji Zeze
We study a gauge fixed action of open string field theory expanded around the universal solution which has been found as an analytic classical solution with one parameter a. For a>…
