Let Θ be the Wigner time reversal operator for spin half and let ϕ be a Weyl spinor. Then, for
a left-transforming ϕ, the construct ζ λ Θ ϕ∗ yields a right-transforming spinor. If instead, ϕ is …

In this review, we give a brief introduction on the aspects of some extra dimension models
and the five-dimensional thick brane models in extended theories of gravity. First, we briey …

A bstract We study soft wall models that can embed the Standard Model and a naturally light
dilaton. Exploiting the full capabilities of these models we identify the parameter space that …

The recent interest in modified theories of gravity, involving some type of non-minimal
coupling to the Ricci scalar and the calculation of cosmological observables in the Einstein …

We study two exactly solvable five-dimensional thick brane world models in pure metric f (R)
gravity. Working in the Einstein frame, we show that these solutions are stable against small …

A bstract In this paper, we consider a coupling mechanism between the kinetic term and the
gravity, in which a coupling function F (R) is introduced into the kinetic term of the five …

It is known that by introducing the Yukawa coupling between the fermion and the
background scalar field, a bulk spin-half fermion can be localized on general Randall …

In this paper, we investigate the braneworld scenario in f (T) gravity with a K-field as the
background field. We consider various different specific forms of f (T) gravity and K-field and …

In this paper, thick branes generated by mimetic scalar field are investigated. Three typical
thick brane models are constructed and the linear tensor and scalar perturbations are …

In this paper, by presenting the potentials of Kaluza-Klein (KK) modes in the corresponding
Schrödinger equations, we investigate the localization and resonances of gravity and …
