Descent Relation of Tachyon Condensation from Boundary String Field Theory

TL;DR

This paper investigates the decay process of lower-dimensional bosonic D-branes using boundary string field theory, revealing that their effective tachyon potential mirrors that of D25-branes, indicating a universal decay profile.

Contribution

It demonstrates that the tachyon potential for lower-dimensional D-branes matches that of D25-branes, providing new insights into brane decay mechanisms within boundary string field theory.

Findings

Tachyon potential profiles are identical for lower-dimensional D-branes and D25-branes.

Boundary string field theory effectively describes D-brane decay processes.

Universal decay behavior observed across different D-brane dimensions.

Abstract

We analyze how lower-dimensional bosonic D-branes further decay, using the boundary string field theory. Especially we find that the effective tachyon potential of the lower-dimensional D-brane has the same profile as that of D25-brane.
