Muon Decay Parameters (TWIST experiment at TRIUMF)
نویسنده
چکیده
The TRIUMF Weak Interaction Symmetry Test (TWIST) experiment has measured the spectrum of positrons from muon decay and determined the decay parameters: ρ = 0.75014 ± 0.00017(stat.) ± 0.00044(syst.) ± 0.00011(η), δ = 0.75067 ± 0.00030(stat.) ± 0.00067(syst.), P π µ ξ = 1.0003 ± 0.0006(stat.) ± 0.0038(syst.). The results are in good agreement with the Standard Model. Future prospects for this measurement are discussed.

Time expansion chamber for characterization of TWIST low energy muon beams
A low mass time expansion chamber (TEC) has been developed to measure distributions of position and angle of the TRIUMF low energy surface muon beam used for the TWIST experiment. The experiment is a high precision measurement of muon decay and is dominated by systematic uncertainties, including the stability, reproducibility, and characterization of the beam. The distributions measured by the ...

متن کاملPredictions for energy distribution and polarization of the positron from the polarized muon decay
The pure lepton decay of the polarized muon is considered, accounting for a new tensor interaction which is outside of the Michel local interactions. This interaction leads to new energy distribution and polarization of the final charged lepton. The presence of such a type of interaction is strongly required for the description of the latest experimental results on the weak radiative pion decay...
متن کاملPrecision planar drift chambers and cradle for the TWIST muon decay spectrometer
To measure the muon decay parameters with high accuracy, we require an array of precision drift detector layers whose relative position is known with very high accuracy. This article describes the design, construction and performance of these detectors in the TWIST (TRIUMFWeak Interaction Symmetry Test) spectrometer.
متن کاملThe TWIST Data Acquisition System at Triumf
The TRIUMF Weak Interaction Symmetry Test (TWIST) is an experiment to measure precisely the Michel parameters describing the energy and angular dependence of positrons emitted from the decay of polarized positive muons. The detector consists of a 2 Tesla superconducting solenoid containing 56 planar chambers for high precision tracking of the positrons through readout of some 4200 multihit TDC ...
