Lowering the string scale in the TeV region provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity can then be accounted by the existence of large internal dimensions, in the submillimeter region, and transverse to a braneworld where our universe must be confined. I review the main properties of this scenario and i...

In this work we deal with thick brane solutions in the warped five-dimensional braneworld scenario a single extra spatial dimension of infinite extent, for class modified theories gravity Lagrange multiplier. We first present action, describe and field equations, outline strategy to find explicit explore stability gravitational sector. The investigation deals mainly construction order framework...

The recently observed accelerating cosmological expansion or ”dark energy” may be either a negative pressure constituent in General Relativity (Dark Energy) or modified gravity (Dark Gravity) without any constituent Dark Energy. Lowor high-curvature modifications of Einstein gravity are distinguished by the spacetime (Ricci) curvature of their vacua. If constituent Dark Energy does not exist, s...

In this paper, we address the issue of finding braneworld solutions in a five-dimensional Horndeski gravity and mechanism localization into brane via “almost massless modes” for suitable values parameters. We compute corrections to Newtonian potential discuss limit where four-dimensional is recovered.

Abstract We study a spin 1/2 fermion in thick braneworld the context of teleparallel f ( T , B ) gravity. Here, is such that $$f_1(T,B)=T+k_1B^{n_1}$$ f 1 ( T , B ) =...
