Abstract
In this work, we study the localization of the vector gauge field in two
five-dimensional braneworlds generated by scalar fields coupled to
gravity. The sine-Gordon like potentials are employed to produce
different thick brane setups. A zero mode localized is obtained, and we
show the existence of reverberations with the wave solutions indicating
a quasi-localized massive mode. More interesting results are achieved
when we propose a double sine-Gordon potential to the scalar field. The
resulting thick brane shows a more detailed topology with the presence
of an internal structure composed by two kinks. The massive spectrum of
the gauge field is revalued on this scenario revealing the existence of
various resonant modes. Furthermore, we compute the corrections to
Coulomb law coming from these massive KK vector modes in these thick
scenarios, which is concluded that the dilaton parameter regulates these
corrections. (C) 2016 Elsevier Inc. All rights reserved.
