Web10 Oct 2014 · Ultra-light axions (ULAs) with masses in the range 10^{-33} eV 10^{-24} eV, ULAs are indistinguishable from standard cold dark matter on the length scales probed, and are thus allowed by these data. For m < 10^{-32} eV, ULAs are allowed to compose a significant fraction of the dark energy.
WebUltralight axion DM can be tested by a future nuclear clock experiment , torsion balances , and atom interferometers such as AION and AEDGE through axion DM's CP-violating couplings. These experiments will probe axion DM–induced oscillations of fundamental constants like electron mass, nucleon mass, and the fine structure constant via the CP … Web1 Mar 2024 · Constraints on ultralight axion particle mass versus axion-photon coupling from our analysis of the MW satellite population (red).
