Igor Pesando
TL;DR
This paper calculates the effective potential for a Dp brane and anti-Dp brane system in type II string theories, demonstrating tachyon condensation and scalar VEVs related to brane separation.
Contribution
It provides an explicit computation of the effective potential at tree level, revealing the dynamics of tachyon condensation and scalar field behavior in brane-antibrane systems.
Findings
Tachyon condenses in the system.
Scalar fields acquire VEV proportional to brane separation.
Effective potential computed explicitly at tree level.
Abstract
We compute the effective potential of a system composed by a Dp brane and a separated anti-Dp brane at tree level in string theory. We show explicitly that the tachyon condenses and that the scalars which describe transverse fluctuations acquire a VEV proportional to the distance.
