Dr. Paolo Crivelli (ETH Zurich, Department of Physics, Institute for Particle Physics and Astrophysics) has recently been awarded an ERC Consolidator grant for his project "Mu-MASS" aiming at a new precision measurement of the Muonium 1S-2S transition energy, ultimately with an improvement by three orders of magnitude. Muonium is the hydrogen-like atom formed by a positive muon and an electron. Its energy levels are, in contrast to the case of ordinary hydrogen, completely dominated by Quantum-Electro-Dynamics (QED) and precision QED calculations are currently ahead of experiment.
