The detection of the axion would be one of the most important events in the history of science. This hypothetical particle can simultaneously solve two fundamental questions of modern physics: the problem of violation of charge-parity (CP) symmetry in the strong interaction and the mystery of dark matter. The axion couples to photons. The search
The detection of the axion would mark a key episode in the history of science. This hypothetical particle could resolve two fundamental problems of Modern Physics at the same time: the problema of Charge and Parity in the strong interaction, and the mystery of dark matter. However, in spite of the high scientific interest in finding it, the search at high radio frequency -above 6 GHz- has been almost left aside for the lack of the high sensitivity technology which could be built at reasonable cost. Until now.
