Classical Solutions in String Field Theory Around the Tachyon Vacuum

  title={Classical Solutions in String Field Theory Around the Tachyon Vacuum},
  author={Leonardo Rastelli and Ashoke Sen and Barton Zwiebach},
In a previous paper [hep-th/0012251] we proposed a simple class of actions for string field theory around the tachyon vacuum. In this paper we search for classical solutions describing D-branes of different dimensions using the ansatz that the solutions factorize into the direct product of a matter state and a universal ghost state. We find closed form expressions for the matter state describing D-branes of all dimensions. For the space filling D25-brane the state is the matter part of the zero… CONTINUE READING
