Muonium Spectroscopy
The electromagnetic interactions of electrons and muons can be described to very high accuracy within the framework of standard theory, in particular within the hydrogen-like muonium atom. Therefore precision measurements allow to test basic interactions in physics and to search for yet unknown forces. Accurate values for fundamental constants can be obtained. Results from experiments on the gr...
متن کاملHigh resolution spectroscopy of muonium
The hydrogen-like muonium atom (μe) consists of a positive muon (μ) and an electron (e−). Since it was first observed by Hughes et al. in 1960 [1], a series of precision experiments could be carried out testing bound state Quantum Electrodynamics (QED) and the nature of the muon as a point-like leptonic particle [2]. Precision values for fundamental constants could be obtained, including the fi...
متن کاملTest of CPT and Lorentz invariance from muonium spectroscopy.
Following a suggestion from Kostelecký et al., we evaluated a test of CPT and Lorentz invariance from the microwave spectroscopy of muonium. Hamiltonian terms beyond the standard model violating CPT and Lorentz invariance would contribute frequency shifts deltanu(12) and deltanu(34) to nu(12) and nu(34), the two transitions involving muon spin flip, which were precisely measured in ground state...
متن کاملMuonium Decay
Modifications of the μ+ lifetime in matter due to muonium (M = μ+e−) formation and other medium effects are examined. Muonium and free μ+ decay spectra are found to differ at O(αme/mμ) from Doppler broadening and O(αme/mμ) from the Coulomb bound state potential. However, both types of corrections are shown to cancel in the total decay rate due to Lorentz and gauge invariance respectively, leavi...
متن کاملPrecision spectroscopy of antiprotonic atoms
Precision spectroscopy of antiprotonic atoms will be an important subject to be pursued at the new antiprotonic decelerator (AD) facility being completed at CERN. In particular, the study of antiprotonic helium atoms, peÿHe2 pHe, ®rst discovered at KEK and studied in detail at low-energy antiproton ring (LEAR), will continue to be one of the most important subjects at AD. Our recent high-reso...
