Split String Formalism and the Closed String Vacuum, II
In this paper we reconsider a class of generalizations of Schnabl’s solution of open bosonic string field theory obtained by replacing the wedge state by an arbitrary combination of wedge states. Contrary to the conclusion of our previous paper hep-th/0611200, we find that under a few modest conditions such generalizations give a sensible deformation of Schnabl’s solution for the closed string ...
متن کاملSplit String Formalism and the Closed String Vacuum
The split string formalism offers a simple template upon which we can build many generalizations of Schnabl’s analytic solution of open string field theory. In this paper we explore two such generalizations: one which replaces the wedge state by an arbitrary function of wedge states, and another which generalizes the solution to conformal frames other than the sliver.
متن کاملA Closed String Tachyon Vacuum ?
In bosonic closed string field theory the " tachyon potential " is a potential for the tachyon, the dilaton, and an infinite set of massive fields. Earlier computations of the potential did not include the dilaton and the critical point formed by the quadratic and cubic interactions was destroyed by the quartic tachyon term. We include the dilaton contributions to the potential and find that a ...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملVacuum String Field Theory
This is a brief review of vacuum string field theory, a new approach to open string field theory based on the stable vacuum of the tachyon. We discuss the sliver state explaining its role as a projector in the space of half-string functionals. We review the construction of D-brane solutions in vacuum string field theory, both in the algebraic approach and in the more general geometrical approac...
