Completing the D7-brane local gaugino action

Understand

Within the ongoing debate about de Sitter (dS) vacua in string theory, different aspects of explicit dS proposals have come under intense scrutiny.

• One key ingredient is D7-brane gaugino condensation, which is usually treated using effective 4d supergravity.
• However, it is clearly more desirable to derive the relevant scalar potential directly from a local 10d Lagrangian.
• Such a local 10d description captures the interactions among the various localized sources and the background fields which are smeared in the 4d Lagrangian.
