Measurement of the Fermi Constant by FAST
An initial measurement of the lifetime of the positive muon to a precision of 16 parts per million (ppm) has been performed with the FAST(see note) detector at the Paul Scherrer Institute. The result is \tau_\mu = 2.197 083 (32)(15) \mus, where the first error is statistical and the second is system...

| description | An initial measurement of the lifetime of the positive muon to a precision of 16 parts per million (ppm) has been performed with the FAST(see note) detector at the Paul Scherrer Institute. The result is \tau_\mu = 2.197 083 (32)(15) \mus, where the first error is statistical and the second is systematic. The muon lifetime determines the Fermi constant, G_F = 1.166 352(9) x 10^-5 GeV^-2 (8 ppm). |
