Precision Measurement of the Positive Muon Lifetime

Precision Measurement of the Fermi Coupling Constant GF

Schematic view of the MuLAN detector.

The Fermi coupling constant is one of the principal parameters of the Standard model and its value determines the strength of all electro-weak processes.

Read a short summary of the theoretical approach here.


The Mulan (Muon Lifetime Analysis) Experiment is a next-generation precision experiment which aims at a 1ppm precision in the determination of the positive muon lifetime. This goal is being pursued by using an almost 4Pi ball of scintillation counters, deadtimeless 500 MHz special-design wave-form digitizers, high throughput data acquisition and the high intensity muon beam at the swiss Paul Scherrer Institute . The Mulan Experiment is an effort of an international collaboration of scientists. The collaboration homepage of the experiment is located at the University of Illinois at Urbana-Champaign.
