Tachyon Condensation on Separated Brane-Antibrane System
We study the effect of tachyon condensation on a brane antibrane pair in superstring theory separated in the transverse direction. The static properties of the tachyon potential analyzed using level truncated string field theory reproduces the desired property that the dependence of the minimum value of the potential on the initial distance of separation between the branes decreases as we inclu...
متن کاملTachyon Condensation on the Brane Antibrane System
A coincident D-brane anti-D-brane pair has a tachyonic mode. We present an argument showing that at the classical minimum of the tachyonic potential the negative energy density associated with the potential exactly cancels the sum of the tension of the brane and the anti-brane, thereby giving a configuration of zero energy density and restoring space-time supersymmetry.

متن کاملTachyon condensation on the intersecting brane-antibrane system
We generalize our study of the tachyon condensation on the brane-antibrane system [hepth/0403147] to the intersecting brane-antibrane system. The supergravity solutions of the intersecting brane-antibrane system are characterized by five parameters. We relate these parameters to the microscopic physical parameters, namely, the number of Dp-branes (N1), the number of D̄p-branes (N̄1), the number o...
متن کاملSupergravity approach to tachyon condensation on the brane-antibrane system
We study the tachyon condensation on the D-brane–antiD-brane system from the supergravity point of view. The non-supersymmetric supergravity solutions with symmetry ISO(p, 1) × SO(9 − p) are known to be characterized by three parameters. By interpreting this solution as coincident N Dp-branes and N̄ D̄p-branes we give, for the first time, an explicit representation of the three parameters of supe...
متن کاملBrane - Antibrane as a Defect of Tachyon Condensation
In a tachyon effective field theory of a non-BPS brane, we construct a classical solution representing a parallel brane-antibrane. The solution is made of a kink and an antikink placed at antipodal points of S. Estimation of the brane energy shows the appearance of an excitation of a string connecting the two branes, even though the theory is Abelian. We performed fluctuation analysis around th...
