A torsion-balance search for ultra low-mass bosonic dark matter

Abstract

We used a stationary torsion balance with a beryllium-aluminum composition dipole to search for ultra low-mass bosonic dark matter coupled to baryon minus lepton number. We set 95% confidence limits on the coupling constant $g_{\mathrm{B}-\mathrm{L}}$ for bosons with masses between $10^{-18}$ and $10^{-16}$ eV/$c^2$ with the best performance at $m_{\mathrm{DM}}=8\times 10^{-18}$ eV/$c^2$ constraining $g_{B-L}(\hslash c{)}^{-1/2}<1\times 10^{-25}$. This provides a complimentary limit to equivalence-principle experiments that search for ultra low-mass bosons as force-mediating particles.
