TL;DR

This paper explores models of hybrid branes in five-dimensional spacetime with two scalar fields, demonstrating how internal structures and splitting phenomena emerge through parameter-controlled interactions, affecting the brane's geometry and potential.

Contribution

It introduces a mechanism for smoothly transitioning from thick to hybrid branes with internal structures, analyzing symmetric and asymmetric scenarios with scalar field interactions.

Findings

Hybrid branes exhibit internal splitting and volcano potential features.

The scalar field interaction parameter controls the brane's internal structure.

Symmetric and asymmetric hybrid brane configurations are characterized.

Abstract

This work reports on models described by two real scalar fields coupled with gravity in the five-dimensional spacetime, with a warped geometry involving one infinite extra dimension. Through a mechanism that smoothly changes a thick brane into a hybrid brane, one investigates the appearance of hybrid branes hosting internal structure, characterized by the splitting on the energy density and the volcano potential, induced by the parameter which controls interactions between the two scalar fields. In particular, we investigate distinct symmetric and asymmetric hybrid brane scenarios.
