We compute the decoupling constant ζ m relating light quark masses of effective n l-flavour QCD to (n l+ 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 GUT scales. With the help of a low-energy theorem ζ m can be used to obtain the effective coupling of a Higgs boson to light quarks with five-loop accuracy. We briefly discuss the influence on Γ (H→ b b¯).
