The gauge algebra of double field theory and Courant brackets
Chris Hull, Barton Zwiebach
We investigate the symmetry algebra of the recently proposed field theory on a doubled torus that describes closed string modes on a torus with both momentum and winding. The gauge…
The boundary state from open string fields
Michael Kiermaier, Yuji Okawa, Barton Zwiebach
We construct a class of BRST-invariant closed string states for any classical solution of open string field theory. The closed string state is a nonlinear functional of the open st…
The off-shell Veneziano amplitude in Schnabl gauge
Leonardo Rastelli, Barton Zwiebach
We give a careful definition of the open string propagator in Schnabl gauge and present its worldsheet interpretation. The propagator requires two Schwinger parameters and contains…
Analytic Solutions for Marginal Deformations in Open String Field Theory
Michael Kiermaier, Yuji Okawa, Leonardo Rastelli +1
We develop a calculable analytic approach to marginal deformations in open string field theory using wedge states with operator insertions. For marginal operators with regular oper…
Analytic Solutions for Tachyon Condensation with General Projectors
Yuji Okawa, Leonardo Rastelli, Barton Zwiebach
The tachyon vacuum solution of Schnabl is based on the wedge states, which close under the star product and interpolate between the identity state and the sliver projector. We use…
Testing Closed String Field Theory with Marginal Fields
Haitang Yang, Barton Zwiebach
We study the feasibility of level expansion and test the quartic vertex of closed string field theory by checking the flatness of the potential in marginal directions. The tests, w…
