Decoupling of heavy quarks at four loops and effective Higgs-fermion coupling
We compute the decoupling constant ζm relating light quark masses of effective nl-flavour QCD to (nl+1)-flavour QCD to four-loop order. Immediate applications are the evaluation of the MS¯ charm quark mass with five active flavours and the bottom quark mass at the scale of the top quark or even at G...
