Linear b-Gauges for Open String Fields
Michael Kiermaier, Ashoke Sen, Barton Zwiebach
Motivated by Schnabl's gauge choice, we explore open string perturbation theory in gauges where a linear combination of antighost oscillators annihilates the string field. We find…
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…
