This paper proposes an optical spectroscopy experiment using muonic hydrogen to detect deviations from Newton's inverse-square law at nanometer scales, potentially revealing extra spatial dimensions as suggested by ADD's model.

Contribution

It introduces a novel spectroscopy-based method to indirectly test for extra dimensions at nanometer scales, surpassing current gravity tests in sensitivity.

Findings

Potential to detect deviations from ISL at nanometer scale

Ability to explore three extra dimensions in ADD's model

Extends the search for extra dimensions beyond current micron-scale tests

Abstract

Considering that gravitational force might deviate from Newton's inverse-square law (ISL) and become much stronger in small scale, we propose a kind of optical spectroscopy experiment to detect this possible deviation and take electronic, muonic and tauonic hydrogen atoms as examples. This experiment might be used to indirectly detect the deviation of ISL down to nanometer scale and to explore the possibility of three extra dimensions in ADD's model, while current direct gravity tests cannot break through micron scale and go beyond two extra dimensions scenario.
