Solar axion search with the CAST experiment / Borghi, S (CERN ; Glasgow U.) ; Arik, E (Dogus U., Kadikoy ; Bogazici U.) ; Aune, S (IRFU, Saclay) ; Autiero, D (CERN ; Lyon, IPN) ; Barth, K (CERN) ; Belov, A (Moscow, INR) ; Beltrán, B (Zaragoza U.) ; Bourlis, G (Hellenic Open U., Patras) ; Boydag, F S (Dogus U., Kadikoy ; Bogazici U.) ; Bräuninger, H (Garching, Max Planck Inst., MPE) et al. /CAST
The CAST (CERN Axion Solar Telescope) experiment is searching for solar axions by their conversion into photons inside the magnet pipe of a LHC prototype dipole. In the phase II, CAST is operating with a buffer gas inside the magnet bore apertures in order to extent the sensitivity of the experiment to larger axion masses. [...]

The 11-years solar cycle as the manifestation of the dark Universe / Zioutas, K. (CERN) ; Tsagri, M. ; Semertzidis, Y.K. (Brookhaven) ; Papaevangelou, T. (IRFU, Saclay) ; Hoffmann, D.H.H. (Darmstadt, Tech. Hochsch.) ; Anastassopoulos, V. (Patras U.)
The solar luminosity in the visible changes at the 10-3 level, following an 11 years period. In X-rays, which should not be there, the amplitude varies 100000 times stronger, making their mysterious origin since the discovery in 1938 even more puzzling, and inspiring. [...]

Search for Solar Axions by the CERN Axion Solar Telescope with 3 He Buffer Gas: Closing the Hot Dark Matter Gap / CAST collaboration
The CERN Axion Solar Telescope (CAST) has finished its search for solar axions with 3^He 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. [...]

Status and perspectives of the CAST experiment / CAST Collaboration
The CERN Axion Solar Telescope (CAST) is currently the most sensitive axion helioscope designed to search for axions produced by the Primakoff process in the solar core. CAST is using a Large Hadron Collider (LHC) test magnet where axions could be converted into X-rays with energies up to 10 keV. [...]

This work provides additional evidence on the involvement of exotic particles like axions and/or other WISPs, following recent measurements during the quietest Sun and flaring Sun. Thus, SPHINX mission observed a minimum basal soft X-rays emission in the extreme solar minimum in 2009. [...]

CAST search for sub-eV mass solar axions with $^{3}$He buffer gas / CAST Collaboration
The CERN Axion Solar Telescope (CAST) has extended its search for solar axions by using 3He as a buffer gas. At T=1.8 K this allows for larger pressure settings and hence sensitivity to higher axion masses than our previous measurements with 4He. [...]
