Anomalous couplings of non-BPS D-branes
Marco Billo', Ben Craps, Frederik Roose
TL;DR
This paper explores how non-BPS D-branes in type II string theory interact with R-R potentials and how tachyon condensation leads to the emergence of BPS D-brane actions.
Contribution
It provides a detailed analysis of the coupling mechanisms of non-BPS D-branes and their transition to BPS D-branes through tachyon condensation.
Findings
Non-BPS D-branes couple to R-R potentials via a specific action.
Tachyon condensation transforms non-BPS D-branes into BPS D-branes with a Wess-Zumino action.
The study clarifies the anomalous couplings involved in this process.
Abstract
Non-BPS type II D-branes couple to R-R potentials via an action that, upon tachyon condensation, gives rise to the Wess-Zumino action of BPS D-branes.
