“…We concentrate on the large negative ϕ region. In this region V Q+iP takes the form (11.7) and 30) where O L (P ) is an appropriate operator in the Liouville field theory which is even under P → −P . Thus the source terms are of the form 31) where |s X 0 ,g denotes some state in the X 0 and ghost CFT.…”

In this review we describe our current understanding of the properties of open string tachyons on an unstable D-brane or brane-antibrane system in string theory. The various string theoretic methods used for this study include techniques of two dimensional conformal field theory, open string field theory, boundary string field theory, non-commutative solitons etc. We also describe various attempts to understand these results using field theoretic methods. These field theory models include toy models like singular potential models and p-adic string theory, as well as more realistic version of the tachyon effective action based on Dirac-Born-Infeld type action. Finally we study closed string background produced by the 'decaying' unstable D-branes, both in the critical string theory and in the two dimensional string theory, and describe the open string completeness conjecture that emerges out of this study. According to this conjecture the quantum dynamics of an unstable D-brane system is described by an internally consistent quantum open string field theory without any need to couple the system to closed strings. Each such system can be regarded as a part of the 'hologram' describing the full string theory.

“…This gives a general procedure for constructing the conserved charge carried by a D-brane corresponding to a specific rigid gauge transformation in closed string theory. The suggestion that the BRST invariance of B| carries information about conserved charges has been made earlier in [52].…”

Two dimensional string theory is known to have an infinite dimensional symmetry, both in the continuum formalism as well as in the matrix model formalism. We develop a systematic procedure for computing the conserved charges associated with these symmetries for any configuration of D-branes in the continuum description. We express these conserved charges in terms of the boundary state associated with the D-brane, and also in terms of the asymptotic field configurations produced by this D-brane. Comparison of the conserved charges computed in the continuum description with those computed in the matrix model description facilitates identification of the states between these two formalisms. Using this we put constraints on the continuum description of the hole states in the matrix model, and matrix model description of the black holes solutions of the continuum theory. We also discuss possible generalization of the construction of the conserved charges to the case of D-branes in critical string theory.

“…They argued that the boundary state should transform under the closed string gauge transformation and found that the gauge invariance requires to add the Dirac-Born-Infeld (DBI) action to (1.1). The authors in [6] also considered a closed SFT with a source term representing a marginal deformation, namely (1.1). They pointed out that an (interacting) closed SFT requires a modification of the deformed boundary state; marginal deformations, which are expected to be solutions in open string theory, are no longer consistent solutions in open-closed string theory.…”

We investigate a classical open-closed string field theory whose open string sector is given by boundary string field theory. The open-closed interaction is introduced by the overlap of a boundary state with a closed string field. With the help of the Batalin-Vilkovisky formalism, the closed string sector is determined to be the HIKKO closed string field theory. We also discuss the gauge invariance of this theory in both open and closed string sides.Comment: 25 pages, 2 figures, comments and a reference added, typos correcte
