Stability of a tachyon braneworld
Gabriel German, Alfredo Herrera-Aguilar, Andre M. Kuerten +2
Within the braneworld paradigm the tachyonic scalar field has been used to generate models that attempt to solve some of the open problems that physics faces nowadays, both in cosm…
Universal spin-1/2 fermion field localization on a 5D braneworld
Nandinii Barbosa-Cendejas, Dagoberto Malagón-Morejón, Refugio Rigel Mora-Luna
In this letter we have proposed a natural way of determine the Yukawa coupling for the 5D bulk action, the form of the function allows us to localize the spin--…
Discrete graviton spectrum from super-exponential cup potentials and their application to braneworld physics
Mariana Carrillo-Gonzalez, Gabriel German, Alfredo Herrera-Aguilar +2
Super-exponential warp factors have been proposed in the context of two-brane models to solve the gauge hierarchy problem of scales by using a compactification scale of the same or…
Study of field fluctuations and their localization in a thick braneworld generated by gravity non-minimally coupled to a scalar field with the Gauss-Bonnet term
Gabriel German, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +2
In this work we study a scenario with a warped 5D smooth braneworld with 4D Minkowski geometry builded from bulk scalar matter non-minimally coupled to gravity with an additional G…
A de Sitter tachyon thick braneworld
Gabriel German, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +2
Among the multiple 5D thick braneworld models that have been proposed in the last years, in order to address several open problems in modern physics, there is a specific one involv…
On gravity localization in scalar braneworlds with a super-exponential warp factor
Mariana Carrillo-Gonzalez, Gabriel German, Alfredo Herrera-Aguilar +1
We show that within tachyonic braneworld models,"super-exponential" warp factors of the form are problematic when dealing with both the finitene…
Anisotropic Inflation in a 5D Standing Wave Braneworld and Dimensional Reduction
Merab Gogberashvili, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +1
We investigate a cosmological solution within the framework of a 5D standing wave braneworld model generated by gravity coupled to a massless scalar phantom-like field. By obtainin…

Merab Gogberashvili, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon +2
We study a smooth cosmological solution within a generalized 5D standing wave braneworld modeled by gravity and a phantom scalar field. In this model the 3-brane is anisotropically…
Thick braneworlds generated by a non-minimally coupled scalar field and a Gauss-Bonnet term: conditions for localization of gravity
Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon, Refugio Rigel Mora-Luna +1
We consider warped five-dimensional thick braneworlds with four-dimensional Poincaré invariance originated from bulk scalar matter non-minimally coupled to gravity plus a Gauss-Bon…
Localization of bulk matter fields, the hierarchy problem and corrections to Coulomb's law on a pure de Sitter thick braneworld
Heng Guo, Alfredo Herrera-Aguilar, Yu-Xiao Liu +2
In this paper we investigate the localization and mass spectra of matter fields with spin 0, 1 and 1/2 on a geometric thick brane generated by pure 4D and 5D positive cosmological…

Merab Gogberashvili, Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon
We present a consistent derivation of the recently proposed 5D anisotropic standing wave braneworld generated by gravity coupled to a phantom-like scalar field. We explicitly solve…
Localization of gravity on a de Sitter thick braneworld without scalar fields
Alfredo Herrera-Aguilar, Dagoberto Malagon-Morejon, Refugio Rigel Mora-Luna
In this work we present a simple thick braneworld model that is generated by an intriguing interplay between a 5D cosmological constant with a de Sitter metric induced in the 3-bra…
