Intersecting Brane Models and Cosmology

TL;DR

This paper explores how intersecting brane models can be applied to cosmology, proposing a D-term inflation scenario with open strings as inflatons and a natural mechanism for baryogenesis via hidden sector anomalies.

Contribution

It introduces a novel D-term inflation model within intersecting brane frameworks and demonstrates a natural baryogenesis mechanism through hidden sector anomalies.

Findings

Open non-vectorlike strings can serve as inflatons in brane cosmology.

Baryogenesis can occur naturally via hidden sector mixed anomalies.

The model provides a straightforward realization of inflation in IBM constructions.

Abstract

We discuss the application of general features of intersecting brane model constructions in cosmology. In particular, we describe a scenario for D-term inflation which arises straightforwardly in IBM constructions wherein open non-vectorlike strings play the role of the inflaton. We also show that baryogenesis driven by hidden sector mixed anomalies can naturally arise in intersecting brane models.
