====== TTP99-18 On the Precise Determination of the Fermi Coupling Constant from the Muon Lifetime ======
 
 
   <hidden TTP99-18  On the Precise Determination of the Fermi Coupling Constant from the Muon Lifetime >   The determination of the Fermi coupling constant, G_F, is examined in the
 light of recently calculated 2-loop QED corrections and planned experiments tomeasure the muon lifetime to a level below 1ppm. The methods used in the
 calculation of the QED corrections are described in detail. Sources of thedominant theoretical and experimental uncertainties are identified. Finally the
 incorporation of G_F into analyses using the full electroweak Standard Model is
 discussed.
