Rolling to the tachyon vacuum in string field theory
arXiv:0705.0013 · doi:10.1088/1126-6708/2007/12/028
Abstract
We argue that the rolling-tachyon solution in cubic OSFT proceeds at late times to precisely the analytic tachyon-vacuum solution constructed by Schnabl. In addition, we demonstrate the relationship between the rolling-tachyon solution and the standard BCFT description by showing that there is a finite gauge transformation which relates the two.
