Search for solar axions by the CERN axion solar telescope with He 3 buffer gas: Closing the hot dark matter gap 2014 Access copy available to the general public Unrestricted The CERN Axion Solar Telescope has finished its search for solar axions with 3He buffer gas, covering the search range 0.64  eV≲ma≲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 gaγ≲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 gaγ, for example by the currently discussed next generation helioscope International AXion Observatory. info:eu-repo/grantAgreement/EC/FP7/240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREX info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03456 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-24058 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 7.512 2014 PHYSICS, MULTIDISCIPLINARY 6 / 78 = 0.077 2014 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Aune, S.
