Sažetak
Hypothetical axion-like particles with a two-photon interaction would be produced in the sun by the Primakoff process. In a laboratory magnetic field they would be transformed into X-rays with energies of a few keV. The CAST experiment at CERN is using a decommissioned LHC magnet as an axion helioscope in order to search for these axion-like particles. The analysis of the 2003 data showed no signal above the background, thus implying an upper limit to the axion-photon coupling of g(a gamma) < 1.16 × 10− 10 GeV− 1 at 95% CL for ma <~ 0.02 eV. The stable operation of the experiment during 2004 data taking allowed us to lower down this parameter to a preliminary value of g(a gamma) < 0.9 × 10− 10 GeV− 1.
