Localization of Fermions on a String-like Defect

TL;DR

This paper investigates how fermions can be localized on a string-like defect in six-dimensional space with a warp factor, analyzing conditions for trapping spin 1/2 and 3/2 fermions in a field theory context.

Contribution

It provides new conditions for localizing fermions of different spins on a string-like defect with a decreasing warp factor in six dimensions.

Findings

Conditions for localizing spin 1/2 fermions established

Conditions for localizing spin 3/2 fermions established

Analysis includes effects of U(1) gauge background

Abstract

We study localization of bulk fermions on a string-like defect with the exponentially decreasing warp factor in six dimensions with inclusion of U(1) gauge background from the viewpoint of field theory, and give the conditions under which localized spin 1/2 and 3/2 fermions can be obtained.
