Abstract

We study a spin 1/2 fermion in a thick braneworld in the context of teleparallel f(T,B)f(T, B) gravity. Here, f(T,B)f(T,B) is such that f1(T,B)=T+k1Bn1f_1(T,B)=T+k_1B^{n_1} and f2(T,B)=B+k2Tn2f_2(T,B)=B+k_2T^{n_2}, where n1,2n_{1,2} and k1,2k_{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 n1,2n_{1,2} and k1,2k_{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.
