Exploring Extra Dimensions in Spectroscopy Experiments

TL;DR

This paper proposes using spectroscopy experiments with high-Z hydrogenic systems and muonic atoms to search for extra spatial dimensions and deviations from Newton's law at small scales, potentially testing theories like ADD's brane world model.

Contribution

It introduces a novel spectroscopic approach to detect extra dimensions and constrain their size within the framework of brane world models.

Findings

Potential to explore more than two extra dimensions

Constraints on the size of extra dimensions

Method to detect deviations from Newton's law

Abstract

We propose an idea in spectroscopy to search for extra spatial dimensions as well as to detect the possible deviation from Newton's inverse-square law at small scale, and we take high-Z hydrogenic systems and muonic atoms as illustrations. The relevant experiments might help to explore more than two extra dimensions scenario in ADD's brane world model and to set constraints for fundamental parameters such as the size of extra dimensions.
