Collaborative Research: Axion Resonant InterAction DetectioN Experiment (ARIADNE) - a continuation proposal

Project: Research project

Project Details

Description

Axions are CP-odd scalar particles appearing in many extensions of the Standard Model. The
well motivated Peccei-Quinn (PQ) axion can explain the smallness of the neutron electric dipole moment,
and is also a promising Dark Matter candidate. Axions and axion-like particles also generate macroscopic
P-odd and T-odd spin-dependent interactions which can be sought in sensitive laboratory experiments. The
Axion Resonant InterAction DetectioN Experiment (ARIADNE) is designed to search for axion-mediated
spin-dependent interactions between nuclei at sub-millimeter ranges. The experiment involves a rotating
non-magnetic mass to source the axion �eld, and a dense ensemble of laser-polarized 3He nuclei to detect
the axion held by NMR. The signal from an axion held can be resonantly enhanced by properly modulating
the axion potential at the nuclear spin precession frequency. The goal of this proposal is to complete
construction of the experiment, bring it through its commissioning phase during which we plan to evaluate
possible systematics, and start the early data taking stage, exploring new paramater space for the PQ axion
