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 کاملDiscovering Learning Analyzing and Predicting Protein Structure
This track focuses on the understanding, and ultimately, the prediction, of protein structure. Papers describe discovery, learning, or analysis approaches that lead to testable predictions, and that quantify or compare predictive accuracy. The papers accepted this year span a wide range of methods that illustrate or investigate most of the approaches currently being used in this eld. Innovative...
متن کامل\μμ decay in the MSSM
We present the results of the complete one-loop computation of the Bd ,s 0 →ll decay rate in the MSSM. Both sources of the FCNC, the CKM matrix and off-diagonal entries of the sfermion mass matrices are considered. Strong enhancement of the branching ratio ~compared to the SM prediction! can be obtained in the large tan b;m t /mb regime in which the neutral Higgs boson ‘‘penguin’’ diagrams domi...
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 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...
