Search for Solar Axions by the CERN Axion Solar Telescope with 3He Buffer Gas : Closing the Hot Dark Matter Gap
The CERN Axion Solar Telescope has finished its search for solar axions with 3He buffer gas, covering the search range 0.64 eV < m_a < 1.17 eV. This closes the gap to the cosmological hot dark matter limit and actually overlaps with it. From the absence of excess X-rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of g_aγ < 3.3×10^(−10) GeV^(−1) at 95% C.L., with the exact value depending on the pressure setting. Future direct solar axion searches will focus on increasing the sensitivity to smaller values of g_aγ, for example by the currently discussed next generation helioscope International AXion Observatory.
