Muonium 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 کاملMuonium 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 کاملMuonium Lifetime and Heavy Quark Decays∗ (lessons Learned from Muonium)
When asked to speak at this Symposium honoring the distinguished scientific career of Vernon Hughes, I knew the word “muon” would have to appear in my title and some property of that particle would provide my theme. Indeed, everyone at Yale knows the answer to I.I. Rabi’s famous question, uttered when confirmation of the muon’s existence was announced: “Who ordered that?” It must have been Rabi...
متن کاملLepton flavor violation in muonium decay and muon colliders in models with heavy neutrinos
We study the lepton-flavor-violating reaction μe → ee within two extensions of the standard model that include heavy neutrinos. The reaction is studied in the low energy limit in the form of muonium decay M → ee and in the high energy regime of a muon collider. The two theoretical models we consider are: model I, a typical see-saw model that violates lepton flavor and number by inclusion of ext...
متن کاملMuonium spectrum beyond the nonrelativistic limit
A generalization of the Gell-Mann–Low theorem is applied to the antimuon-electron system. The bound state spectrum is extracted numerically. As a result, fine and hyperfine structure are reproduced correctly near the nonrelativistic limit (and for arbitrary masses). We compare the spectrum for the relativistic value α = 0.3 with corresponding calculations in light-front quantization.
