Fermion localization mechanisms in f(T,𝒯 )-brane

Abstract

In this work, we investigate two mechanisms for locating fermions on the brane in a modified teleparallel gravity [Formula: see text], where [Formula: see text] is the torsion scalar and [Formula: see text] is the trace of the energy–momentum tensor. The first mechanism is a Yukawa-type minimal coupling between the fermion and the background scalar field. The second mechanism is a nonminimal coupling between the fermion and the torsion. The geometric coupling presents a greater sensitivity to the influence of torsion and to the trace of the energy–momentum tensor.
