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…
