Search for solar axions
Abstract
We have searched for a flux of axions produced in the Sun by exploiting their conversion to x rays in a static magnetic field. The signature of a solar axion flux would be an increase in the rate of x rays detected in a magnetic telescope when the Sun passes within its acceptance. From the absence of such a signal we set a 3σ limit on the axion coupling to two photons gaγγ≡1/M<3.6×10-9 GeV-1, provided the axion mass ma<0.03 eV and <7.7×10-9 GeV-1 for 0.03 <ma<0.11 eV.
