Searches for exotic interactions with the nEDM experiment

TL;DR

This paper reports on using ultracold neutrons in the nEDM experiment to search for signs of exotic physics such as Lorentz and CPT violation or dark matter interactions, by measuring the neutron's electric dipole moment.

Contribution

It introduces a novel application of ultracold neutrons in the nEDM experiment to probe for exotic interactions beyond the Standard Model.

Findings

No evidence of Lorentz or CPT violation found.

Constraints placed on dark matter interaction parameters.

Improved limits on the neutron electric dipole moment.

Abstract

Ultracold neutrons were used to search for signals indicating the violation of Lorentz and CPT invariance or the existence of dark matter using the spectrometer to search for an electric dipole moment of the neutron.
