Embedding of two de-Sitter branes in a generalized Randall Sundrum scenario

TL;DR

This paper generalizes the Randall-Sundrum model by exploring new warp factor behaviors, brane tension constraints, and relations between fundamental coupling constants and mass scales.

Contribution

It introduces a generalized scenario with novel warp factor behaviors and establishes new relations between coupling constants and mass scales.

Findings

New warp factor behaviors identified

Constraints on brane tension with positive sign

Relations between ppa_4, ppa_5, Higgs, and Planck masses

Abstract

In this work it is studied a generalization of Randall Sundrum model. It is obtained new behaviors of {\it warp factor}, constraints in that the strong brane has tension of positive sign and, new relations between the coupling constants $\kappa_4$, $\kappa_5$ and between the Higgs and Planck masses.
