====== TTP03-39 Two Loop Electroweak Bosonic Corrections to the Muon Decay Lifetime ======
 
 
   <hidden TTP03-39  Two Loop Electroweak Bosonic Corrections to the Muon Decay Lifetime > A review of the calculation of the two loop bosonic corrections to
 $\Delta r$ is presented. Factorization and matching onto the Fermi model
 are discussed. An approximate formula, describing the
 quantity over the interesting range of Higgs boson mass values from
 100~GeV to 1~TeV is given.
