MuLan: Towards a 1ppm muon lifetime measurement
Kevin R. Lynch (the MuLan Collaboration)
TL;DR
The MuLan experiment aims to measure the positive muon lifetime with 1ppm precision, enabling a highly accurate determination of the Fermi Constant within the Standard Model.
Contribution
This paper reports progress towards achieving a 1ppm measurement of the muon lifetime, a significant improvement over previous measurements.
Findings
Progress in experimental setup and data collection
Initial results indicate measurement precision approaching 1ppm
Potential to determine the Fermi Constant to 0.5ppm
Abstract
The MuLan experiment will measure the lifetime of the positive muon to 1ppm. Within the Standard Model framework, this will permit a determination of the Fermi Constant to 0.5ppm. I present an update on our progress and achievements to date.
