Abstract

We analyzed a 6.7-yr span of data from a rotating torsion-pendulum containing ≈1023 polarized electrons to search for the "wind" arising from ultralight, axionlike dark matter with masses between 10-23 and 10-18 eV/c2. Over much of this range we set a 95% confidence limit Fa/Ce>2×1015 eV on the axionlike decay constant.
