Higgs Driven Geodetic Evolution/Nucleation of de-Sitter Brane

TL;DR

This paper explores how a Higgs potential uniquely drives the evolution of a de-Sitter brane, leading to novel horizon structures and supporting the no-boundary proposal, diverging from traditional cosmological constant models.

Contribution

It introduces a Higgs-driven mechanism for de-Sitter brane evolution, highlighting the role of a hairy horizon and the quartic potential structure in cosmological modeling.

Findings

Higgs potential drives de-Sitter brane evolution

Hairy horizon characterizes deviation from Einstein gravity

Quartic potential supports no-boundary proposal

Abstract

Geodetic evolution of a de-Sitter brane is exclusively driven by a Higgs potential, rather than by a plain cosmological constant. The deviation from Einstein gravity, parameterized by the conserved bulk energy, is characterized by a hairy horizon which serves as the locus of unbroken symmetry. The quartic structure of the potential, singled out on finiteness grounds of the total (including the dark component) energy density, chooses the no-boundary proposal.
