Fermion localization in higher curvature spacetime

TL;DR

This paper demonstrates that in a higher curvature braneworld model with dilaton coupling, left-handed fermions can be naturally localized on the brane without additional fields, due to the effects of Gauss-Bonnet gravity.

Contribution

It introduces a mechanism for fermion localization in higher curvature gravity models without external fields, leveraging dilaton coupling and Gauss-Bonnet terms.

Findings

Left-handed fermions are localized on the brane naturally.

Higher curvature terms influence fermion localization.

Dilaton coupling plays a key role in the localization process.

Abstract

Fermion localization in a braneworld model in presence of dilaton coupled higher curvature Gauss-Bonnet bulk gravity is discussed. It is shown that the lowest mode of left handed fermions can be naturally localized on the visible brane due to the dilaton coupled higher curvature term without the necessity of any external localizing bulk field.
