Muon capture on the proton and deuteron
By measuring the lifetime of the negative muon in pure protium (H), the MuCap experiment determines the rate of muon capture on the proton, from which the proton’s pseudoscalar coupling gp may be inferred. A precision of 15% for gp has been published; this is a step along the way to a goal of 7%. This coupling can be calculated precisely from heavy baryon chiral perturbation theory and therefor...
متن کاملMuon Capture on the Deuteron The MuSun Experiment MuSun Collaboration
We propose to measure the rate Λd for muon capture on the deuteron to better than 1.5% precision. This process is the simplest weak interaction process on a nucleus that can both be calculated and measured to a high degree of precision. The measurement will provide a benchmark result, far more precise than any current experimental information on weak interaction processes in the two-nucleon sys...
متن کاملRadiative Muon Capture by a Proton in Chiral Perturbation Theory
The first measurement of the radiative muon capture (RMC) rate on a proton was recently carried out at TRIUMF. The TRIUMF group analyzed the RMC rate, Γ RMC, in terms of the theoretical formula of Beder and Fearing, and found the surprising result that gP ≡ fP (q2 = −0.88mμ) is 1.5 times the value expected from PCAC. To assess the reliability of the theoretical framework used by the TRIUMF grou...
متن کاملFaddeev Calculations of Proton-Deuteron Radiative Capture with Exchange Currents
pd capture processes at various energies have been analyzed based on solutions of 3N-Faddeev equations and using modern NN forces. The application of the Siegert theorem is compared to the explicit use of πand ρ-like exchange currents connected to the AV18 NN interaction. Overall good agreement with cross sections and spin observables has been obtained but leaving room for improvement in some c...
متن کاملMuon Lifetime and Muon Capture
We present an introduction to the MuLAN and MuCAP experiments at PSI, which aim at high precision determinations of two fundamental Weak Interactions parameters: the Fermi constant GF and the induced pseudoscalar form factor gp, respectively. MULAN MUON LIFETIME The Fermi coupling constant GF is one of the fundamental constants of the Standard Model. GF is obtained from the muon lifetime via a ...
