Search for 14.4 keV solar axions emitted in the M1-transition of Fe-57 nuclei with CAST
We have searched for 14.4 keV solar axions or more general axion-like particles (ALPs), that may be emitted in the M1 nuclear transition of Fe-57, by using the axion-to-photon conversion in the CERN Axion Solar Telescope (CAST) with evacuated magnet bores (Phase I). From the absence of excess of the monoenergetic X-rays when the magnet was pointing to the Sun, we set model-independent constraints on the coupling constants of pseudoscalar particles that couple to two photons and to a nucleon g(a gamma)vertical bar-1.19 g(aN)(0) + g(aN)(3)vertical bar < 1.36 x 10(-16) GeV-1 for m(a) < 0.03 eV at the 95% confidence level
