Test of fundamental symmetries via the Primakoff effect

The three neutral pseudoscalar mesons, π0, η and η′, represent one of the most interesting systems in strong interaction physics. A study of the electromagnetic properties of these mesons provides a sensitive probe of the symmetry structure of QCD at low energy. A comprehensive experimental program...
