F-term Inflation in M-theory with Five-branes

TL;DR

This paper investigates F-term inflation within M-theory frameworks, demonstrating that successful slow-roll inflation requires non-zero F-terms of five-brane moduli fields, unlike in models without these fields.

Contribution

It shows that incorporating five-brane moduli fields with non-zero F-terms enables slow-roll inflation in M-theory, which was not possible without them.

Findings

Slow-roll condition not satisfied without five-brane moduli.

Non-vanishing F-terms of five-brane moduli enable slow-roll inflation.

Highlights the importance of five-brane moduli in M-theory inflation models.

Abstract

We study F-term inflation in M-theory with and without five-brane moduli fields. We show the slow rolling condition is not satisfied in M-theory without five-brane moduli fields, but it can be satisfied in the case with non-vanishing F-terms of five-brane moduli fields.
