Zusammenfassung der Projektergebnisse
The project was devoted to precision tests of quantum electrodynamic theory of simple atoms and evaluation of the precision data in order to improve our knowledge on the values of fundamental constants and for searches for new physics. The project objects are a development of theory of two-body atoms and of the anomalous magnetic moment of the electron and muon. The results were obtained on the interpretation of the results on muonium hyperfine interval, on theory of the Lamb shift of hydrogen, on various contributions to QED observable. The constraint on the electric charge of the neutron and neutrino was studies. It was demonstrated that the constraint made in the Review of Particles Properties are inconsistent and that the neutrino constraint is based on the erroneous interpretation. The consistent set of corrected constraints is presented.
