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 …

It is shown that the introduction of a suitable function in the higher-dimensional gauge field
action may be used in order to achieve gauge bosons localization on a thick brane. The …

This work tries to find out thick brane solutions in braneworld scenarios described by a real
scalar field in the presence of a scalar-kinetic term F (X, ϕ)= Xϕ m with a single extra …

We present new results on the localization of gauge fields in thick brane models. The four-
dimensional observable universe is considered to be a topological defect which is …

We follow the Chumbes–Holf da Silva–Hott mechanism to study the (quasi) localization of
the U (1) gauge field on the Bloch brane. The localization and resonances of the U (1) …

This work presents new results about the graviton massive spectrum in two-field thick
branes. Analyzing the massive spectra with a relative probability method we have firstly …

In this work, we investigate probe scalar field models preserving covariance on fixed, static
background geometries that present hyperscaling violation properties. We develop a first …

In this paper the whole kink varieties arising in several massive non-linear Sigma models
whose target space is the torus S 1× S 1 are analytically calculated. This possibility …

It is well known that the U (1) gauge vector field, with the standard five-dimensional (5D)
action, cannot be localized on Randall-Sundrum-like braneworlds with an infinite extra …
