The Scales of Brane Nucleation Processes

TL;DR

This paper discusses the scales involved in brane nucleation processes in type IIB string theory models with stabilized moduli, arguing these processes are unlikely to be captured by effective field theory.

Contribution

It provides an analysis of the scales of brane nucleation in flux compactifications, highlighting limitations of effective field theory in describing these processes.

Findings

Brane nucleation scales are significant in flux compactifications.

Effective field theory may not adequately describe brane nucleation processes.

Implications for understanding string landscape dynamics.

Abstract

The scales associated with Brown-Teitelboim-Bousso-Polchinski processes of brane nucleation, which result in changes of the flux parameters and the number of D-branes, are discussed in the context of type IIB models with all moduli stabilized. It is argued that such processes are unlikely to be described by effective field theory.
