Abstract

Measurement of a neutron electric dipole moment (nEDM) is a sensitive probe of CP-violating physics beyond the Standard Model. Such a measurement could provide clues as to the origins of the matter-antimatter asymmetry. Spin dressing is a technique where an off-resonant oscillating magnetic field is applied to a spin or ensemble of spins to modify their effective gyromagnetic ratio. This technique was proposed for use in the neutron electric dipole moment experiment at the spallation neutron source (nEDM@SNS) to increase statistical sensitivity and mitigate systematics. Here we present a comprehensive study of spin dressing in the context of EDM measurement from theoretical, computational, and experimental perspectives.
