Overview of the neutron electric dipole moment experiment at Los Alamos National Laboratory

ORAL

Abstract

The standard model of particle physics predicts an exceedingly small value for the electric dipole moment of the neutron (nEDM). However, beyond standard model theories tend to predict larger values of the nEDM, possibly within the reach of upcoming experiments. This talk will present an overview and status of the nEDM experiment under development at the Los Alamos National Laboratory (LANL) ultracold neutron source and targeting a measurement uncertainty of $3\times 10^{-27}$~$e$-cm. The experiment features a double-cell geometry, 199Hg co-magnetometry, external optical magnetometers, precision holding field coil and gradient coils, and a large, state-of-the-art magnetically shielded enclosure. Some of these features will be covered in more detail in other talks or posters at this conference, with this talk providing a broader view of the experiment.
