Abstract: (Elsevier)
It is discussed whether an axion-like excitation can be the source for the monoenergetic positrons observed at GSI. Although a direct extension of the original Peccei-Quinn model is experimentally ruled out, it is possible to construct an alternative model which avoids all previous axion bounds, involving quarkonia decays, K decays, nuclear decays and beam-dump experiments. The model predicts, at some level, the possibility of flavor-changing interactions involving charmed quarks and suggests an appealing regularity for the quark and lepton masses. The expectations of the model for resonant e + e − scattering are briefly discussed.
