Abstract

We study a spin 1/2 fermion in a thick braneworld in the context of teleparallel f(T, B) gravity. Here, f(T, B) is such that f(1)(T,B) = T + k(1)B(n1) and f(2)(T,B) = B + k(2)T(n2), where n(1,2) and k(1,2) are parameters that control the influence of torsion and the boundary term. We assume Yukawa coupling, where one scalar field is coupled to a Dirac spinor field. We show how the n(1,2) and k(1,2) parameters control the width of the massless Kaluza-Klein mode, the breadth of non-normalized massive fermionic modes and the properties of the analogue quantum-potential near the origin.
