Test of quantum field theory, particularly high precision test of quantum electrodynamics and the Standard Model; making use of simple systems such as the anomalous magnetic moments of the electron and muon, and the hyperfine structure of the muonium

Research Focus

At present the tenth-order QED correction term to the anomalous magnetic moment of the electron is being evaluated. When completed it will enable us to determine the intrinsic magnetic property of the electron to a precision exceeding 1 part in 10 billion. As a byproduct it will provide by far the most precise value of the fine structure constant, one of the most important constants of the Nature, ever measured.
