We study the BSFT actions by using an analytic continuation in momentum space. We compute various two- and three-point functions for some low-lying excitations including massive states on BPS/non-BPS D-branes. The off-shell two-point functions for the tachyon, the gauge field and the massive fields are found to reproduce the well-known string mass-shell conditions. We compare our action with the tachyon actions previously obtained by the derivative expansion (or the linear tachyon profiles…

D-branes and string field theory

In this thesis we study the D-brane physics in the context of Witten's cubic string field theory. We compute first few terms the low energy effective action for the nonabelian gauge field A, from

Matrix Model from String Field Theory

We show that the boundary string field theory (BSFT) on unstable D0-branes in 2d string theory is equivalent to the double scaled c = 1 matrix model (i.e. quadratic action), even though we naively

On the general action of boundary (super)string field theory

We reconstruct boundary superstring field theory via boundary states. After a minor modification of the fermionic two-form, all the equations needed for Batalin-Vilkovisky formulation are simply

c = 1 matrix model from string field theory

We show that the boundary string field theory (BSFT) on unstable D0-branes in 2d string theory is equivalent to the double scaled c = 1 matrix model (i.e. quadratic action), even though we naively

We study the tree level scattering or emission of n closed superstrings from a decaying non-BPS brane in Type II superstring theory. We attempt to calculate generic n-point superstring disk

We reformulate bosonic boundary string field theory in terms of boundary state. In our formulation, we can formally perform the integration of target space equations of motion for arbitrary field

Taming the Tachyon in Cubic String Field Theory

We give evidence based on level-truncation computations that the rolling tachyon in cubic open string field theory (CSFT) has a well-defined but wildly oscillatory time-dependent solution which goes

Low energy effective actions and tachyon dynamics from string field theory

In this thesis we show how to calculate off-shell low energy effective actions and how to study the dynamics of the tachyon from string field theory. We discuss how to obtain an effective action for

Tachyon condensation in boundary string field theory at one loop

We compute the one-loop partition function for quadratic tachyon background in open string theory. Both closed and open string representations are developed. Using these representations we study the

Rolling Tachyon

We discuss construction of classical time dependent solutions in open string (field) theory, describing the motion of the tachyon on unstable D-branes. Despite the fact that the string field theory

Brane-antibrane action from boundary string field theory

In this paper we give the boundary string field theory description of brane-antibrane systems. From the world-sheet action of brane-antibrane systems we obtain the tachyon potential and discuss the

The study of open string tachyon condensation in string field theory can be drastically simplified by making an appropriate choice of coordinates on the space of string fields. We show that a very

Motivated by recent discussions of actions for tachyon and vector fields related to tachyon condensation in open string theory we review and clarify some aspects of their derivation within the sigma

EXACT POTENTIAL AND SCATTERING AMPLITUDES FROM THE TACHYON NONLINEAR BETA FUNCTION

We compute, on the disk, the non-linear tachyon β-function, βT, of the open bosonic string theory. βT is determined both in an expansion to the third power of the field and to all orders in

Covariant string field theory.

It is proved that the on-shell physical amplitudes at the tree level are completely independent of the string length parameter ..cap alpha... the zero-slope limit of the covariant string action as well as of the BRS transformation is calculated completely off the mass shell.

Universality of the tachyon potential

Using string field theory, we argue that the tachyon potential on a D-brane in bosonic string theory in arbitrary background has a universal form, independent of the boundary conformal field theory
