High Purity Pion Beam at TRIUMF
A. Aguilar-Arevalo, M. Blecher, D. A. Bryman +14
An extension of the TRIUMF M13 low-energy pion channel designed to suppress positrons based on an energy-loss technique is described. A source of beam channel momentum calibration…
Measurement of P_{mu}xi in Polarized Muon Decay
TWIST Collaboration, B. Jamieson, R. Bayes +37
The quantity P_{mu}^{pi}xi, where xi is one of the muon decay parameters and is the degree of muon polarization in pion decay, has been measured. The value P_{mu}^{pi}xi =…
Measurement of the Muon Decay Parameter delta
TWIST Collaboration, A. Gaponenko, R. Bayes +45
The muon decay parameter delta has been measured by the TWIST collaboration. We find delta = 0.74964 +- 0.00066(stat.) +- 0.00112(syst.), consistent with the Standard Model value o…
Measurement of the Michel Parameter in Muon Decay
TWIST Collaboration, J. R. Musser
The TWIST Collaboration has measured the Michel parameter in normal muon decay, . In the Standard Model, = 3/4. Deviations from this value require…
