Search for Axionlike Dark Matter through Nuclear Spin Precession in Electric and Magnetic Fields
Tijdschriftbijdrage - Tijdschriftartikel
We report on a search for ultralow-mass axionlike dark matter by analyzing the ratio of the spinprecession
frequencies of stored ultracold neutrons and 199Hg atoms for an axion-induced oscillating
electric dipole moment of the neutron and an axion-wind spin-precession effect. No signal consistent with
dark matter is observed for the axion mass range 10−24 ≤ ma ≤ 10−17 eV. Our null result sets the first
laboratory constraints on the coupling of axion dark matter to gluons, which improve on astrophysical
limits by up to 3 orders of magnitude, and also improves on previous laboratory constraints on the axion
coupling to nucleons by up to a factor of 40.
