概要

• 論文の詳細を見る

• 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 > -1/2, we are able to reproduce open string scattering amplitudes in the theory fixed in the Siegel gauge. At a = -1/2, all scattering amplitudes vanish and there is no open string excitation in the gauge fixed theory. These results support the conjecture that the universal solution can be regarded as a pure gauge or the tachyon vacuum solution.
