Primordial nucleosynthesis in higher dimensional cosmology

TL;DR

This paper explores how primordial nucleosynthesis and element formation are affected in higher dimensional cosmology, revealing that temperature decay rates differ from standard models, potentially impacting early universe physics.

Contribution

It introduces a generalized Friedmann-Robertson-Walker model in higher dimensions and analyzes its implications for early universe nucleosynthesis.

Findings

Temperature decays more slowly in higher dimensional cosmology

Potential nontrivial effects on primordial physics

Implications for early universe element formation

Abstract

We investigate nucleosynthesis and element formation in the early universe in the framework of higher dimensional cosmology. For this purpose we utilize a previous solution of the present author, which may be termed as the generalized Friedmann-Robertson-Walker model. We find that temperature decays less rapidly in higher dimensional cosmology, which we believe may have nontrivial consequences \emph{vis-a-vis} primordial physics.
